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.

iASAP Analysis of Air-Sensitive Compounds via Inert Sampling Techniques

Many chemical reactions carried out by synthetic chemists involve air-sensitive compounds such as metal catalysts and organometallics and must therefore be carried out in a glove box or using a Schlenk line to prevent oxidation and hydrolysis. Sampling and transportation of these samples to a mass spectrometer by an Atmospheric Solids Analysis Probe (ASAP ®)…
