    กระดาษทดสอบ EDTA (0 – 400 ppm.)

    Quick and easy determination of EDTA

    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
