Environmental Test Kits
QUANTOFIX® test strips meet all requirements of a modern rapid test. The colour of the reactive pad changes depending on the concentration of an analyte in the sample. The evaluation is usually carried out visually by comparison of the reaction colour with a multi-stage colour scale. These test strips are immediately ready-to-use. They do not require additional accessories. The test strips are intended for single use, maintenance or calibration are not required.

  • Results within seconds: Just dip, wait and read against multi-stage colour scale
  • Always ready to use: No accessories necessary for evaluation
  • Safe results: Desiccant in the stopper for optimal protection of the strips against humidity

These test strips are 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 (Ethylendiaminetetraacetate) 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, it is used to control, if EDTA has completely rinsed out. This may dramatically reduce the rinsing 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 and conversion factor: 1 mg/l EDTA = 0,7 mg/l NTA
