expression® CMS: Mass Spectrometers Designed for Chemists

With decades of mass spectrometry and chemistry expertise, Advion Interchim Scientific has produced a family of compact mass spectrometers designed for the chemist. The affordability, small size and ease of use make them ideal for use directly at the chemist’s bench, giving immediate answers and informed decisions instead of waiting.

The Advion Interchim Scientific expression® compact mass spectrometer (CMS) is a fast and easy analytical tool for the organic chemist. Ideal for fast reaction monitoring, the expression® CMS features a single quadrupole that can adapt to multiple ionization sources in seconds, including both ESI and APCI. The mass spectrometer works in a variety of applications, including food and beverage, pharmaceutical, biomedical, peptides and proteins, drug discovery and more. The expression® CMS offers a variety of novel sampling techniques, including:

  • Direct mass analysis of TLC plates in 30 seconds at the push of a button with Plate Express™
  • One-touch analysis of solids and liquid samples with the ASAP® probe
  • LC/CMS
  • Many more options and configurations to suit your needs

Learn more about the different sample techniques available with the expression® CMS, including fast assay methods for liquids, solids, gases, and even air-sensitive compounds.

Rapid Determination of Aflatoxins in Corn Flour by LC/CMS

Aflatoxins (B1, B2, G1, G2) produced by certain fungi (Aspergillus flavus and Aspergillus parasificus) are toxic metabolites which have been associated with various diseases, such as aflatoxicosis, in livestock, domestic animals and humans throughout the world. Many methods can be used for Aflatoxins analysis, including TLC, HPLC, immunoassay, LCMS etc. Of all the methods, the LC/MS method is considered the preferred technique because of its high selectivity and sensitivity. In this presentation, a simple, cost effective LC/CMS analytical approach is described for the determination of Aflatoxins.

Direct Sample Analysis of “Fizzy Drinks”

Chemists are tasked with quickly identifying compounds created, ensuring quality of products or evaluating safety. Current techniques are adequate, but not all offer speed, data quality or ease-of-use provided by the expression® Compact Mass Spectrometer (CMS). The expression® CMS with the direct analysis probe (ASAP®) offers chemists the ability to rapidly analyze solids, liquids and powders without tedious and time consuming sample preparation.

Determination of Emerging Nitrogenous Economic Adulterants in Milk Proteins by HPLC/Compact Mass Spectrometry

Economic adulteration of milk involves adulteration with nitrogen-rich compounds to interfere with the widely used Kjeldahl protein assay and inate the total protein content result for economic gains. The economic adulteration issue garnered global attention during the melamine scandal in 2007 which resulted in the sickening and deaths of infants fed with adulterated milk powder. Therefore the ability to rapidly screen milk ingredients in the manufacturing plants for potential economic adulterants is becoming increasingly important.

The current analytical method of choice is based on UPLC-MS/MS which is both expensive and requires considerable expertise for routine use. A simpler and more cost-effective alternative for frontline screening has been developed. The method uses HILIC-based HPLC and single quadrupole mass spectrometry detection to determine the presence of melamine, cyromazin, ammelide and ammeline in milk-based protein commodities.
