PhotoCheck testsættet er fremstillet til test af nøjagtigheden af bølgelængden i alle Merck's fotometre og spektrofotometre. Den kan bruges som en sekundær standard til instrumenttest i henhold til DIN/ISO 9000 og ISO 14000. De stabile farvede opløsninger kan bruges til test af følgende indstillinger af spektrofotometerfiltre og bølgelængde: 445 og 446 nm, 520 og 525 nm og 690 nm. Nøjagtigheden af bølgelængdeindstillingen og lineariteten af ekstinktionsmålingen kontrolleres med 4 opløsninger pr. bølgelængde. Sporbarheden af disse testopløsninger til internationale standarder garanteres ved undersøgelse i et referencefotometer, som kontrolleres mod den primære standard (NIST standard). Disse værdier dokumenteres korrekt og indgår i leveringen af sættet.

Potassium bromide is transparent from the near UV to long wave IR wavelengths. In IR-spectroscopy, solid samples which are difficult to melt or dissolve in any suitable IR-transmitting solvent, are analysed by grinding with potassium bromide powder, and pressing into a disc. This procedure has a high quality demand of the used potassium bromide. Potassium bromide Uvasol® is adjusted to a mean particle size of 150 μm. This is sufficient for the preparation of perfectly good pellets without the need for further pre-treatment and the associated risk of contamination. It also retains its powdery form over a period of years if stored in an airtight condition. Its physical suitability for pelletising is checked by a special application test and its chemical purity established by full spectrum FT-IR analysis.
