Abstract
Abstract By comparing column dimentions and outlet linear velocity, U out, of a gas chromatograph with those specified in a known protocol, operating parameters can be calculated for the gas chromatograph which maintain the peak elution order, retention times and the resolution obtained in the protocol, thus simplifying the identification of unknown compounds.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
132 words
A method for automatic configuration of the operating parameters of a gas chromatograph in response to the manual input of new column parameters such that the chromatographic output corresponds to the chromatographic output of a know chromatographic method having both known column parameters and known operating parameters, comprising the steps of; storing known column and operating parameters of the known chromatographic method into the gas chromatograph; and inputting the new column parameters into the gas chromatograph; and calculating new operating parameters from said stored column and operating parameters and said inputted column parameters; and automatically configuring the gas chromatograph with said calculated hew operating parameters such that the chromatographic output of said gas chromatograph with said new column and operating parameters is the same as with said know column and operating parameters.
Claim 2
Dependent Claim
32 words
The method for automatic configuration of the operating parameters of a gas chromatograph as in claim 1, wherein one of said operating parameters is the column outlet linear velocity (u out ).
Claim 3
Dependent Claim
28 words
The method for automatic configuration of the operating parameters of a gas chromatograph as in claim 1, wherein one of the column parameters, the phase ratio, remains constant.
Claim 4
Dependent Claim
58 words
The method for automatic configuration of the operating parameters of a gas chromatograph as in claim 1, wherein the step off calculating new operating parameters further comprises the step of calculating the new column outlet linear velocity and the new column average outlet linear velocity, and the ratio of the new column parameters to the known column parameters.
Claim 5
Dependent Claim
24 words
The method for automatic configuration of the operating paramaters of a gas chromatograph as in claim 1, wherein the peak elution temperature is maintained.
Claim 6
Dependent Claim
51 words
The method for automatic configuration of the operating parameters of a gas chromatograph as in claim 1, wherein said step of automatically configuring the gas chromatograph further comprises the step of adjusting integrator chart speeds to effect registration between output peaks and proportional peak widths between new and existing chromatographic outputs.
