9:00am- 12:00pm (Half Day)

Preprocessing, How To Do and Not To Do

Woody Barton, Light Light Solutions, LLC

Facilitated in cooperation with Coblentz and SAS


The first things one learns when applying NIR spectroscopy and chemometrics to analytical problems is that you need to “preprocess the data”. If spectra were perfect and spectrometers produced identical spectra of identical samples and all reference data represented the analyte’s concentration in the spectra, then preprocessing would not be needed. Baseline offsets, particle size, heterogeneity and the vagaries of analytical procedures on different samples means it’s necessary to remove any interferences that do not belong to the analyte’s spectrum. When preprocessing is done correctly the variability is removed from the spectra but when done incorrectly, can introduce features into the spectrum that could be interpreted as actual chemical signatures. This course will look at the common preprocessing techniques and how they impact the spectra and the models. We will be providing spectra and the ability to practice these techniques so each student should bring a laptop.

9:00am- 4:00pm (Full Day)

Searching Infrared and Raman Spectra

James de Haseth, Light Light Solutions, LLC

Facilitated in cooperation with Coblentz and SAS


In a general sense, spectral searching is a simple operation. An unknown spectrum is presented to the search system software, the spectral databases are searched, and a result presented. This simple operation in no way explains how to optimize the process to arrive at the best, ideally the correct, identification. There is more than one search algorithm, so which one should be used? What if the unknown compound is not in the database? What if the unknown spectrum represents a mixture? How can we proceed to find these answers? This course will address these issues and more. Participants will be provided with a two-week trial copy of Wiley KnowItAll® Software to use during and after the course. It will not be possible to provide laptop computers for participants; therefore, the software will be sent to the participants shortly before the course so that it can be installed on a Windows 10 laptop computer.

Monday, September 27

9:00am- 12:00pm (Half Day)

Open-Source Electronics in Chemical Instrumentation

James Grinias, Rowan University

Samuel Foster, Rowan University


This course serves as an introduction to the use of low-cost microcontrollers (e.g. Arduinos) and single-board computers (e.g. Raspberry Pi) in chemical instrumentation. Examples of how these types of devices can be used to control light sources, valving, pumps, electrodes, sensors, data acquisition modules, and movement systems will be discussed. Strategies for hardware-software interfaces that can be implemented for simple user control of these functions will also be described. Attendees will additionally learn many practical tips on setting up and troubleshooting electronic control systems, primarily focused on common mistakes related to circuit design and software coding. As part of the course, students will have the opportunity to build a simple colorimetric cuvette reader that is operated with a microcontroller to conduct simple absorbance measurements of dyes.


1:00- 4:00pm (Half Day)

Fundamentals and Applications of Surface Enhanced Raman Spectroscopy (SERS)

Annie Dowgiallo, SRI International


This course serves as an introduction to surface enhanced Raman spectroscopy (SERS) and its relevance to a variety of applications such as pharmaceuticals, defense, medical, and the environmental. SERS is a versatile technique in its ability to identify chemical species and obtain structural information, impacting fields such as polymer and materials science, biochemistry and biosensing, catalysis, and electrochemistry. Attendees will learn the basics of Raman, SERS, nanotechnology, and ways to utilize this powerful spectroscopic tool.


Problems with FT-IR Spectra and How to Avoid Them

Ellen Miseo, TeakOrigin, Inc.

Jenni Briggs, Pike Technologies 

Facilitated in cooperation with Coblentz and SAS


Users of FT-IR spectrometers may have received little or no formal training in spectroscopy and therefore cannot distinguish between “good” and “bad” spectra. In this course, we will show many of the problems that are commonly encountered with FT-IR spectra measured by inexperienced (and often experienced!) users and show how to avoid them. Problems can appear from the instrument, the sample accessory and/or presentation. Since the bulk of the samples that are currently analyzed are done by Attenuated Total Reflection we will cover it in detail. We will also address common problems associated with other accessories. This year we will also be including a “tricks of the trade” component to the class.

9:00am- 4:00pm (Full Day)

Basics of Multivariate Modeling of Spectroscopic Data

Michael Roberto, Northwest Analytics


This workshop will introduce attendees to the fundamentals of chemometrics, with specific examples devoted to the application of spectroscopic data. Expect a dynamic workshop, with plenty of strained metaphors and just the right amount of matrix math. Topics covered will include mathematical foundations, appropriateness of use, preprocessing and transformations, data visualization and exploration, steady state determination, and regression modeling.


9:00am- 12:00pm (Half Day)

Introduction to ICP-MS: Fundamentals, Best Practice and Tips and Tricks

Dula Amarasiriwardena, Hampshire College

Facilitated in cooperation with SAS


This course will introduce to inductively coupled plasma-mass spectrometry (ICP-MS) fundamentals and operational principles. Course content includes fundamentals, theory, instrumentation, practice, troubleshooting hints, as well as common applications. Analytical merits and limitations of each method will be presented.


1:00- 4:00pm (Half Day)

Introduction to Infrared, Raman, and Near Infrared Spectroscopy

James de Haseth, Light Light Solutions, LLC

Facilitated in cooperation with Coblentz and SAS


This course will present the origins of spectral bands in Infrared, Raman, and NIR spectra. This will start with a discussion of fundamental molecular vibrations and where these are present in mid-infrared and Raman spectra and explain how overtone and combination bands can appear in the NIR as well as in mid-infrared and Raman spectra. Some direct guidelines will be presented to show which transitions are allowed. This will not be a theoretical discussion that involves mathematics or quantum mechanics, but rather an understanding of the physical phenomena that led to the development of the mathematical approaches. A key issue to the collection of good spectra is an understanding how spectrometers work. Such topics include instrument components, resolution, spectral range, measurement sensitivity, instrumental effects on spectral lineshape, instrument sources of errors, and effects of mathematical manipulation of spectra.


Wednesday, September 29

9:00am- 12:00pm (Half Day)

Course content includes fundamentals, theory, instrumentation, practice, troubleshooting hints, as well as common applications. We will also briefly discuss sample preparation methods available for spectrochemical analysis. Analytical merits and limitations of each method will be presented.


2-Part Career Development

Part I: Beyond the Beaker

Jeanita Pritchett, JSP Coaching and Consulting, LLC


The Beyond the Beaker Workshop is designed to help undergraduate and graduate students as well early career professionals explore the skills needed to advance their STEM careers. Looking beyond developing technical expertise, the interactive workshop helps attendees gain self-awareness, confidence, and clarity so they may emerge as leaders in their fields. While navigating through school or the early stages of a STEM career, emphasis is typically placed on the technical aspects needed within the field. Countless hours are spent learning how to develop mastery of a hands-on technique to exhibit expertise in the field. However, advancing a STEM career and moving up the leadership ladder requires additional skills outside of the laboratory. The Beyond the Beaker Workshop equips participants with tools and strategies that they can apply to advance their careers.

Part II: Dynamic Skills for Success

Lori Ana Valentín, New York State Police


“The only difference between a stumbling block and a stepping stone is how you use it.” This American proverb emphasizes the importance of maintaining a healthy perspective that empowers you to take full advantage of all of your opportunities. As chemists, most of us have embraced the value of hard work and grit. We have high standards and our work is under constant scrutiny. These conditions can lead to perfectionism and even imposter syndrome. Our academic institutions prepare us with the technical skills and intellectual opportunities to be successful, but how prepared are we to navigate the unexpected stressors of life – a pandemic, illness, or loss? Learn how to cultivate and maintain three critical skills for lifelong success: Self-Love, Perspective, and Resilience. This interactive workshop will empower you to address current challenges, overcome future challenges, and find opportunity and inspiration in even the darkest moments.


1:00- 4:00pm (Half Day)

3D printing for microfluidic devices

Greg Nordin, Brigham Young University

Adam Woolley, Brigham Young University


The workshop will introduce 3D printing, types of 3D printers, and how they can be used to create microfluidic devices, together with a comparison to traditional fabrication methods. Based on their extensive experience, the presenters will then discuss the current state-of-the art of component miniaturization and integration of 3D printed active elements such as valves and pumps into more complex device designs. Attendees will leave with an understanding of the opportunities and limitations of 3D printing for microfluidic device fabrication, an appreciation of the challenges in creating 3D printed microfluidic devices, and guidance on whether 3D printing microfluidics is right for their application.


Innovations in Beer Quality through Instrumental Analysis

Ben Chambers, Newport Craft Brewing and Distilling

My presentation will cover methods of analysis for breweries and the production of beer. Attendants could find this topic interesting as brewing beer has been around since the ancient Sumerians (as we know of), yet only in the last few centuries have we started to apply scientific analyses for the purposes of QA/QC as well as R&D. Today several accredited universities and third-party labs, in addition to countless small to large functional brewery labs have been established with standard methods and instrumentation for analysis. I will break down what these are and explain how they keep today’s culture enjoying safe and controlled beer products. This workshop will have a limited amount of registrants.
