5 Now load the Gas calibration_liquefied gas method in the sam-
ple table of your tiamo™ workplace. Select the designation of the
gas type that was newly added and enter a target value for the sam-
ple gas volume (recommended range: approx. 20 L). This is the value
that is displayed with the internal nitrogen calibration and not the
actual gas volume of your sample. This value should be approx. 1.5
times the gas amount (in grams) which you want to convey through
the instrument.
6 Tare the balance and start the method. After the target value has
been reached, a prompt appears in which you have to enter the
weight difference after gas infeed. The prefix does not matter for
this.
