Select sequence sample types

Sample types are used in a sequence to describe each item being processed. You select sample types in the sequence table or as part of a sequence template.

Sample type descriptions:

• Sample – A sample with unknown amounts of analytes being analyzed.
• Blank – A sample without any analytes that is treated like a sample. It is used as a signal-to-noise reference for all subsequent samples and for system suitability. If an ISTD method is being used, then the Blank usually contains the internal standard.
• Double blank – Sometimes called "solvent blank", it is used to prove that no chromatographic artifacts are coming from the instrument flow path for that particular column.
• Cal. Std. (Calibration standard) – A sample with a known amount of analyte that is used as a reference to create or update a calibration table in the processing method.
• QC check – A sample with a known amount of analyte that is used to verify and prove that the calibration is correct.
• Spike - A sample with a known amount of standard added.
• Sys Suit - A sample that is run to demonstrate that system is working correctly as expected. This sample is typically run before running other samples.
