Plate Express

For full product details and specs, please download our product note featuring the Plate Express TLC Plate Reader:

Plate Express™ is a device that provides a simple, automated means of obtaining mass spectra directly from TLC plates, combined with Advion’s expression® compact mass spectrometer (CMS) creating a technique known as TLC/CMS. Using this technique chemists can quickly and confidently identify products even in complex mixtures without additional sample preparation.

  • Identify spots in <1 minute
  • Avoid the risk of overloading the mass spectrometer – TLC spots contain the ideal amount of sample for mass spectrometry
  • Software controlled – spectra obtained within a few mouse clicks
  • Simplify the process of obtaining spectra – ideal for multi-user labs

UHPLC/CMS Analysis of Casein Proteins in Milk

In this application note, the Advion UHPLC/CMS system is used to analyze casein proteins in whole milk extract to separate and detect β-casein-B, -A1, and -A2, as well as K-casein and αs1-casein variants. This method is also suitable for a quick, relative quantitation of the β-casein-B, -A1, and -A2 variants in standards of β-casein.

Simple LC/MS Analysis of Carbohydrates

Introduction There are many separation and detection methods are available for the determination of saccharides. These include GC-MS with derivatization, HPLC-UV with derivatization, HPAEC-PAD (High-performance anion-exchange chromatography coupled with pulsed amperometric detection), and LC-MS. The availability of a sensitive and accurate method is still a challenge. For an LC-MS method, given the high polarity, hydrophilicity…

Urinary Cortisol Quantitation Using Ultra High Pressure Liquid Chromatography/Compact Mass Spectrometry

Introduction Cortisol is an important steroid hormone produced from cholesterol in the adrenal cortex. Its secretion is closely regulated by the Adrenocorticotropic hormone (ACTH). Most cortisol is protein-bound, and only unbound cortisol is excreted in urine. Measurement of cortisol in urine is typically used in the diagnosis of Cushing’s syndrome, a disorder of hypercortisolism. Although…
