Checking the halide trap and drying tube
Make sure that the drying tube is filled with magnesium perchlorate and quartz wool
is only present in the lower part of the tube.
For C detection install the halide trap filled with copper and brass wool in the gas
path.
For S detection remove the halide trap and connect an empty U tube instead.
The halide trap absorbs sulfur. Therefore, the use of the halide trap must be evaluated
for
C/S detection. Dependent on the matrix it is recommended for low sulfur concentrations not
to use a halide trap, but the halide trap should be installed in the gas path for higher conce
