667-UV10 Sodium Iodide liquid filter to check stray light at 259nm

The sodium iodide liquid filter consists of 10g/l sodium iodide in pure water. This filter is suited to check the stray light of a spectrometer in the spectral range between 210 nm and 259 nm, its cut off is at about 259 nm.

Please note

Currently there are different methods used in the European Pharmacopoeia (EP) and the United States Pharmacopoeia (USP) to determine the stray light

  • Testing accoring to EP method (European Pharmacopoeia):
Measurement of sodium idodide (UV10) against reference filter pure water (UV12)

  • Testing accoring to USP 857 (U.S. Pharmacopoeia):
Measurement of sodium iodide (UV10, PL 10mm) against reference filter sodium iodide (UV10H, PL 5mm)

Article-no.EP Set: 667101 (667001 (UV10) / 667012 (UV12))
USP- Set: 667101H (667001 (UV10) / 667001H (UV10H))
