Alternate Detection Techniques for HPLC

UV-Visible detection has been the standard for HPLC analysis for decades. This type of detection relies on a compound’s ability to absorb UV (or visible) light at certain wavelengths. But what about compounds that do not contain a chromaphore? Or compounds that have too low of a concentration to be detected via UV-Visible or where enantioselectivity is required? This webinar outlines alternate detection techniques such as fluorescence, refractive index, circular dichroism and evaporative light scattering to provide chemists with detection solutions outside of the UV-Visible realm.

FTIR Microscopy

This introductory webinar covers FTIR imaging. After a quick recap of FTIR theory and instrumentation, sample preparation, techniques and objectives are discussed. Additionally, hardware such as sample stages, detectors, and complimentary microscopy techniques are reviewed.

SFC Theory and Applications

This webinar covers the theory of supercritical fluids including their properties and advantages when applied to supercritical fluid chromatography (SFC). The design and requirements of the system hardware explains similarities to other chromatographic techniques like HPLC. Finally, a variety of industry applications is discussed highlighting the advantages of SFC for rapid analytical analyses and highly efficient preparative purifications.

Raman Microscopy and Imaging

This webinar takes a look into hardware and software necessary to obtain Raman images and mapping. Some of the applications reviewed include:

  • Mapping of pharmaceutical tablets
  • Identification and characterization of microplastics
  • Contamination of silicon wafer
  • Stress in semiconductor devices
  • Images of carbon materials

FTIR Theory, Instrumentation, and Techniques

In this webinar, Dr. James Burgess gives a presentation on FTIR Theory and Instrumentation, which includes an introduction to the theory of IR spectroscopy –  wavelength range, bond energies, and functional groups. A detailed introduction to the design concepts of the instrument follows. Finally, sampling techniques such as ATR (attenuated total reflectance), transmission, specular reflectance, and diffuse reflectance are discussed.

Circular Dichroism Measurement Optimization

Part 2 of our circular dichroism webinar series highlights sample considerations, measurement parameter optimization, and data processing functions including:

  • Selecting a buffer/solvent
  • The importance of monitoring the HT voltage
  • What is D.I.T.?
  • Optimizing the spectrum S/N
  • Subtracting a background spectrum
  • Converting to MRME

Vibrational Circular Dichroism

This webinar provides a review of vibrational circular dichroism, instrumentation and measurement parameters such as:

  • Types of sample that are amenable to vibrational circular dichroism
  • Effects of concentration and solvent selection
  • Measurement optimization and minimization of artifacts
  • Data analysis and comparison with ab initio calculation

Circular Dichroism Theory and Instrumentation

This introductory webinar provides a review of circular dichroism theory and instrumentation basics, as well as common biological applications including:

  • Structural characterization of proteins
  • VHH Antibody stability evaluation
  • Thermal stability studies
  • Structural characterization of nucleic acids
  • Microassay methods

Fluorescence Theory and Instrumentation

Whether working in a teaching, research, or industrial lab, getting high-quality, reproducible data – in which you have confidence – is essential. This introductory webinar provides a review of foundational fluorescence concepts and how to use this knowledge to optimize fluorescence. Theory and instrumentation for steady-state photoluminescence is discussed along with practical pointers for parameter selection to get the most out of your data.

Raman Theory and Instrumentation

This webinar begins with an introduction to the Raman Effect, including how visible light can give vibrational information. Raman instrumentation is thoroughly examined detailing function and options for lasers, gratings, and detectors. Finally, some time is given to imaging/sampling options common to Raman microspectrometers.
