It is highly recommend to periodically validate a moisture sorption instrument using a certified humidity reference to ensure precise and reliable results at any time.
Reference Material: Microcrystalline Cellulose
The humidity validation kit of ProUmid includes 5 vials of microcrystalline cellulose (MCC). Each vial contains 500 mg MCC humidity reference. The cellulose was tested in a stability study, validated in a round robin test and was certified as a company internal reference standard. For further information on the certification of the MCC as a reference material, please download the corresponding application note AN_18-02 MCC Reference Certification
In-line Humidity Validation
With the ProUmid multi-sample DVS instruments, the periodically required humidity validation can be conveniently accomplished in-line with regularly scheduled measurements, using a free sample dish. Running time-consuming separate validation tests is not required. The in-line measurement not only validates the calibration of the instrument, but also the generated data of the current measurement.
