ALMSCO International has recently released two new application notes.

The first, Application Note 013, describes an innovative approach to GC peak integration, in which ions contributing to chromatographic peaks are intelligently distinguished from each other and from background interference. This results in cleaner spectra that allow accurate area determinations without recourse to time-consuming ‘quant ion’ analysis.

The second, Application Note 014, describes the use of BenchTOF-dx and TargetView to detect polycyclic aromatic hydrocarbons (PAHs) in diesel exhaust particulate. The sensitivity and ‘classical’ spectra produced by BenchTOF-dx allow accurate identification of PAHs with near-identical fragmentation patterns, while TargetView enables GC profiles of trace-level analytes to be visualised even when hidden under much more abundant components.
