Methods

Method Directory Structure

A method comprises a group of files stored in the method directory.

The methods subdirectory comprises all the method subdirectories that have a

.M extension. Additional methods subdirectories can be added using the

preference settings.

Method files with the .MTH extension contain parameter sets and are in

UNICODE format. The file INFO.MTH comprises the method control

parameters.

Method files containing the instrument parameters have the name of the

related analytical module. For example:

Table 5 Method file examples

LC1090.MTH Comprises the 1090 acquisition method.

GC5890.MTH Comprises the 5890 acquisition method.

HPCE1.MTH Comprises the acquisition method for the Capillary Electrophoresis.

DAD1.MTH Comprises the acquisition method for the HP 1090.

FLD1.MTH Comprises the acquisition method for the HP1046 fluorescence detector

ECD1.MTH Comprises the acquisition method for the HP1049 electrochemical

detector

ADC1.MTH Comprises the Agilent 35900 acquisition method. If two identical

instruments are configured, the method files are called ADC1.MTH,

ADC2.MTH.

DAMETHOD.REG For data evaluation.

LALS1.REG Comprises parameters for the Agilent 1100/1200 Series autosampler. The

method files for the other Agilent 1100/1200 Series modules follow the

same convention lxxx1.reg where xxx is the module acronym.
