Purpose

 

This reference uses Starna’s proven and universally accepted UV and visiblereference materials for the qualificationof 96-well plate readers.

 

Description and Discussion

 

This device contains six Starna liquid CRMs in a black anodised aluminium microplate, manufactured to the Society of Biomolecular Screening (SBS) dimensional standards
for a 96-well plate. The heat sealed, liquid filled cell formatutilises 5mm path length cells that have a unique (patent applied for) bubble trap to minimise measurement errors. Potassium dichromate solution is used as an absorbance reference, and holmium oxide solution as a wavelength reference. These references are accepted by Pharmacopoeias and Standardisation Bodies as evidence of instrumentqualification. Full details, spectra, etc of the individualreference materials may be found in the appropriate Starna data sheets.

The standard product has the following configuration ofreference position and CRM:

 

Position Reference 

C2 - H2

Potassium dichromate 0.001M perchloric acid blank

C4 - H4

Potassium dichromate 40mg/l in 0.001M perchloric acid

C6 - H6

Potassium dichromate 80mg/l in 0.001M perchloric acid

C8 - H8

Potassium dichromate 120mg/l in 0.001M perchloric acid

C10 - H10

Potassium dichromate 160mg/l in 0.001M perchloric acid

C12 - H12

Holmium oxide (8%) in 10% perchloric acid

Absorbance values for the potassium dichromate referencesare certified at 235, 257, 313, & 350nm and range fromapproximately 0.1 A to 1.0 A. The Holmium solution has 14certified peak values from 240 nm to 640 nm.

Any standard format Starna sealed liquid CRM is available in the Starna microplate format. These include references for wavelength accuracy, absorbance accuracy, stray light and resolution. Please contact Starna for more information.
