Protocols
Spectrophotometric determination of proline by the Ninhydrin method, per EN 1141 and German Food and Feed Code §64 LFBG 31.00-7.
Quantify selenium in water using this photometric test and a clear, filtered sample to measure the results at 445 nm.
Articles
Compare PAH determination in olive oil: traditional GB 5009.265-2021 method vs. faster, simpler SPE with Supelclean™ EZ-POP NP; both meet criteria.
