n-Heptan, Uvasol® for spectroscopy, Supelco®
Supplier: Merck
Accurate analytic results in UV/VIS and infrared spectroscopy depend on the use of very pure solvents for sample preparation. The Uvasol® solvents range has been specially designed for spectroscopy and other applications requiring solvents of the highest spectral purity. The refinement process allows a greater degree of security in applications and avoids misinterpretation of analytical results caused by traces of UV, IR and fluorescence contamination. Uvasol® solvents offer best UV transmittance. In all specifications the minimum transmittance for 5 typical wavelengths are identified. Furthermore the transmittance is specified in accordance with Reag. Ph Eur and ACS.

Spectroquant® PhotoCheck, Supelco®
Supplier: Merck
PhotoCheck har utvecklats för testning av våglängdsnoggrannhet hos alla fotometrar och spektrofotometrar från Merck. Kan användas som en sekundär standard för testning av instrument enligt DIN/ISO 9000 och ISO 14000. De stabila färglösningarna kan användas för att testa följande spektrofotometerfilter och våglängdsinställningar: 445 och 446 nm, 520 och 525 nm samt 690 nm. Noggrannheten hos våglängdsinställningen och linjäriteten kontrolleras med 4 lösningar per våglängd. Spårbarheten till internationella standarder är garanterade genom mätning mot den primära standarden (NIST-standard). Certifikat medföljer.
