Quick and easy determination of EDTA. Features: • This test strip is for the rapid and reliable determination of EDTA, NTA and other complexing agents in solutions. • The easy dip-and-read-procedure provides a reliable result within 15 seconds. • Complexing agents like EDTA (Ethylendiaminetetraaccetate) or NTA (Nitrilotriacetic acid) have replaced phosphates as additives in washing and cleaning solutions. • QUANTOFIX® EDTA is therefore ideal to check the concentration of washing and cleaning solutions. • In proteomics labs EDTA is also used to regenerate Ni- and Co-precharged chromatography columns (FPLC columns) which are used to purify recombinant proteins. • Prior to the successive analysis, QUANTOFIX® EDTA is used to control, if EDTA has completely rinsed out. • This may dramatically reduce the rinse time and therefore increase the throughput and the capacity. • The following complexing agents can also be determined: Nitrilotriacetic acid (NTA), Cyclohexanedinitrilo-(1,2)-tetraacetic acid, Diethyltrinitrilopentaacetic acid, Bis(aminoethyl)glykol-ether-N,N,N’,N’-tetraacetic acid. • Conversion factor: 1 mg/l EDTA = 0,7 mg/l NTA. Specifications: • Presentation: Tube of 100 test strips. • Color reaction: red → yellow. • Gradation: 0 · 100 · 200 · 300 ·400 mg/l EDTA.
