IR/MS-CRYOLECT4800 Brings The Best Of Both Worlds Together
This Cryolect 4800 display screen compares the mass spectrum ofo-cresol with the IR fingerprint region of the same compound in the liquid, vapor and matrixisolated states. Note the wealth of clearly defined information within the matrix-isolated spectrum, shown in green.

You know the individual limitations of GC/MS and GC/FT-IR. GC/MS has picogram detection limits, but needs IR confirmation to identify many isomers and ring compounds. Traditional GC/FT-IR has always had molecular speci ficity, but not the sensitivity you demand. Even together, they can't provide proof-positive identification because light pipe techniques don't equal GC/MS sensitivity. And that includes GC-dedicated light pipes such as the IRD.1 Now know this: only the Cryolect 4800IR/MS combines the specificity you've always needed with the revolutionary sensitivity that only matrix isolation can bring to FT-IR. That's because only matrix isolation enhances IR bands with 100 times more intensity and extraordinarily sharper resolution than ever before. That means only the Cryolect 4800 — whether working with your GC/MS or our optional mass selective detector — can fully meet your needs for thorough, fail-safe analysis of virtually any organic compound. And the Cryolect 4800 is supported by an extensive matrix-isolated spectral library backed by Mattson Instruments' exclusive relationship with Fluka Chemicals. The new Cryolect 4800 IR/MS. Users in laboratories everywhere are regulating the environment, identifying flavor chemicals, determining com petitive formulations, in fact "... solving analytical problems daily which, in the past, were considered impossible.
