Potassium Dichromate

The performance check for the DropSense96 forms part of the diagnostic tools provided by Trinean to check the functional status of the instrument. A full description of these tools can be found in the ‘Diagnostics’ section of the DropSense96 user manual.

The DropQuant software includes a performance validation procedure to check the photometric accuracy and precision of the DropSense96 in combination with DropPlate consumables. This check is based on the read-out of a gravimetrically prepared solution of NIST traceable potassium dichromate (K2Cr2O7) with a verified absorbance at 350nm.

It is recommended to perform this check every 4-6 months or after transportation of the DropSense96 to ensure that the instrument is performing within its specifications. When the test report shows results out of specification, a recalibration by your local service engineer will be required.
