expressionL CMS

for large molecule analysis

The expression family of compact mass spectrometers provide essential information quickly and improves the chemist’s workflow.  For chemists requiring a higher mass range, the expressionL is the ideal mass detector for large molecule applications with a mass range up to m/z 2,000. Because of multiple charge ESI it is possible to analyze large biomolecules of several 10s of kDa.

Unrivalled flexibility and utility

  • Peptide synthesis, batch and online reaction monitoring
  • QC of proteins
  • Oligonucleotides
  • Polymer chemistry
  • Natural products

Advion’s unrivalled expertise in mass spectrometry provides a mass spec solution just for chemists. Whether you are a biopharmaceutical company, academic teaching/research lab, or any industry requiring routine mass assays, the expressionL CMS delivers high performance in a compact, easy-to-use package at an affordable price.

Toluene-Assisted APCI and Elemental Composition Prediction Using a Compact Mass Spectrometer

OVERVIEW Toluene-assisted APCI (TAPCI) can generate (M)+· and (M+H)+ ions from analytes that cannot be ionized by ESI or APCI. Elemental formula prediction at 250 ppm accuracy and isotope distribution matching by TAMI (Tal Aviv Molecule Identifier) supports analyte identification. Combining both TAPCI and TAMI on the expression compact mass spectrometer (CMS) provides a cost-effective…

LC/CMS Determination of Polycyclic Aromatic Hydrocarbons (PAHS) in Water (EPA 610 Mix)

Polycyclic aromatic hydrocarbons (PAHs) are neutral compounds containing multiple aromatic fused rings that are present in fossil fuels and can be formed from the incomplete combustion of organic material. In recent years, it has been well documented that several PAHs can be potentially carcinogenic via exposure or ingestion. The EPA has classified seven PAHs (benzo[a]pyrene, benz[a]anthracene, chrysene, benzo[b]fluoranthene, benzo[k]fluoranthene, dibenz[a,h]anthracene, and indeno[1,2,3-cd]pyrene) as Group…
