Selected Ion Flow Tube Mass Spectrometry (SIFT-MS) eliminates chromatography by applying ultra-soft chemical ionization. In doing so, SIFT-MS analyzes gas and headspace samples instantly using chemical separation, rather than physical separation.
Chromatography-free operation coupled with multiple ionization mechanisms from eight instantly switchable reagent ions (H3O+, NO+, O2+, O–, O2–, OH–, NO2–, and NO3–) enables extremely diverse compounds to be analyzed in one simple, seamless operation.
Consider, for example, the following SIFT-MS applications:
|Application||Examples of target compounds or classes of compounds|
|Fumigant and toxic industrial chemical detection||Ammonia, chloropicrin, ethylene oxide, formaldehyde, hydrogen cyanide, methyl bromide, phosphine, sulfuryl fluoride (Vikane®)|
|All-in-one environmental analysis||Aldehydes (e.g. formaldehyde, acetaldehyde), acid gases (e.g. hydrogen chloride, hydrogen fluoride, sulfur dioxide), carbon dioxide, nitric oxide, VOCs|
|Comprehensive odor analysis||Hydrogen sulfide, organosulfur compounds, sulfur oxides, ammonia, amines, aldehydes, organic acids|
Chromatographic techniques cannot tackle all analytes in these applications in one analysis, nor can they achieve quantitative analysis to part-per-trillion levels in a matter of seconds.
SIFT-MS provides unique application opportunities.
