Introducing a new way to analyze and present mass spectral data, the Advion Peak Express™ patented software uses the delta spectrum (ΔS) to quickly and automatically detect significant peaks within mass spectra based on their relative change in intensity over time instead of their absolute intensity.
- Find impurities and minor components that would otherwise be missed
- Find unknowns in complex samples such as natural products
- Automatically find adducts, dimers, fragments, side reactions, and other unexpected compounds in real time and post processing
- Control mass-directed purification without providing an exact mass
- Get extracted ion chromatogram (XIC) quality data while scanning the entire mass range
- 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 analysis platform for a wide range of compounds.
Many compounds in organic synthetic chemistry either have no functional group, a C=O carbonyl group, or protected functional groups and are difficult to ionize by ESI or APCI for detection by mass spectrometry. TAPCI has been shown to ionize compounds to (M)+· and (M+H)+ protonated molecules not accessible by ESI or APCI MS analysis. The ionization is believed to include a charge transfer reaction in the APCI plasma region of the source. Elemental formula prediction using TAMI allows analyte identification on a single quadrupole mass spectrometer with mass accuracy in the 250 ppm range, isotope pattern analysis and auto comparison to NIST databases. Here, we investigate the use of both techniques on the expression CMS as an attractive and cost-effective solution for analyte identification covering an increased compound space.
Quant Express, an addition to Advion’s user-friendly Mass Express 4.0 software suite, features quantitation to create a fully integrated software system for expression CMS users.
The CheMS user interface simplifies the mass spectrometry experience and makes it more accessible in chemistry and biochemistry laboratories. This allows the chemist to obtain optimal data without needing to be an expert in mass spectrometry.
Available with the Advion expression® compact mass spectrometer (CMS) is a fast and easy tool that is ideal for the teaching environment — Students simply select an ionization method for effortless instrument setup at the click of a button.
