Instrument Specifications
The instrument has multiple, free programmable measuring ranges. The calibration can be defined by user within the ranges given below. Liquid phase measurements provides calibration by liquid peroxide standard for example:
: 0 to 30.0 µg/l : 0 to 300.0 mg/l : 0 to 3.0 mg/l*
* Higher concentrations on request.
|
Detection limit:
