The
PE Nelson Turbochrom Data Acquisition Software is configured
to allow the usage of two types of method files. Instrument
Method files are used to control relays configured to control
sampling of calibration gases, humidified blanks and ambient
air samples automatically (Figure 1). Processing Method files
are used to control the data reduction, containing the component
names, retention times and calibration factors.
Merlin
supplies configured instrument and processing methods for each
system and optimizes them according to the specific hardware
being used at a given site. Instrument Method files are integral
to the Humidified Blank and Calibration system hardware (see
below). With this hardware the system can be scheduled to automatically
run calibration blends and humidified blanks each day as well
as retention time standards at operator defined intervals.
