Lab Exercise: Commands

Registers, Objects, and Tables

150

to obtain a single numeric element from a table.

Type:

pk_width=tabval(ChromReg[1],"intresults",2,"width") <enter>

Print pk_width <enter>

You obtained the peakwidth of the second integrated chromatographic peak.

3) Use the commands to obtain the name of the 4th compound from the

quantification results table "compound" found in the ChromRes register. To

get this information, you must print a report first. By doing this, the variables

will be stored in ChromRes. Print a report now if you haven’t already done

so.

Name$=Tabtext$(ChromRes,"compound",4,"name")<enter>

Print Name$ <enter>

To obtain the quantified amount for the compound use adifferent column

name to access the same table.

Amount=TabVal(ChromRes,"compound",4,"amount") <enter>

Print Amount <enter>

4) To access the compounds retention time, you will need to reference the "peak"

table in ChromRes. You cannot simply use reference index "4" because there

are more integrated chromatographic peaks than in the "compound" table.

Type the following to obtain the retention time:

FirstPeak=TabVal(ChromRes,"compound",4,"FirstPeak") <enter>

RT=TabVal(ChromRes,"peak",FirstPeak,"MeasRetTime") <enter>

Print RT <enter>

1 2 ... 153 154 155 156 157 158 159 160 161 162 163 ... 210 211
