EM Quant® Calcium TestTest strips and reagents for the detection and semi-quantitative determination of calcium ions GeneralThe calcium test is ideal for performing rapid semi-quantitative determinations of calcium in aqueous media. It is also useful in quality control as a means of measuring concentrations of calcium compounds. These may be incorporated into animal feeds and fertilizers, or may be used as cleaners or polishes, or whiteners in enamels, glassware and porcelain. Calcium also has an important physiological role, e.g. in human bone tissue, a fact reflected by an EEC recommendation that drinking water should contain 100mg/liter calcium. Principle of the MethodThe calcium detection is based on the formation of a complex between calcium ions and glyoxal-bis-2-hydroxyanil in the presence of hydrogen peroxide.

Safety PrecautionsKeep reagent 2 (32% sodium hydroxide solution) away from the skin. In the event of contact, rinse well immediately with plenty of water. Seek immediate medical attention if substance enters the eye. Influence of AnionsThe determination is not disturbed by less than:
The determination is not disturbed by less than 1000mg/l Br-, BrO3-, Cl-, ClO, ClO3-, CN- , CrO42-, [Fe(CN)6]4- , I- , IO3-, Mo7O246-, N3-, NO2-, NO3-, OCN-, PO4-3, SCN-, S2O52-, S2O82-, SeO32-, WO42-, acetate, ascorbate, succinate or tartrate. Influence of CationsThe determination is not disturbed by less than 1000mg/l Al3+, As3+, Ba2+, Bi3+, Mg2+, NH4+, Pb2+, Rb+, Sb3+, Sr2+ or VO2+. Interfering discolorations are caused by more than: 400mg/l Ag+ (black) 300mg/l Au3+ (gray-green) 10mg/l Cd2+ (blue-violet) 50mg/l Co2+ (dark violet) 350mg/l Cr3+ (light green) 10mg/l Cu2+ (gray) 100mg/l Fe2+ (green) 100mg/l Fe3+ (brown) 100mg/l Hg+ (green-brown) 100mg/l Hg2+ (gray) 50mg/l Mn2+ (gray-yellow) 50mg/l Ni2+ (brown) 25mg/l Pb2+ (green) 200mg/l Sn2+ (pink) 25mg/l Zn2+ (brown) More than 10 mg/l Ce3+/4+ , Ti4+ or Zr+ prevents the detection of less than 25 ppm Ca2+. Elimination of InterferenceInterfering anions can be removed by using Amberlite® IRA-400 ion exchanger, about 2 mmol of anions being absorbed per g of ion exchanger. Allow 20ml of the weakly acidic to neutral sample solution to run slowly (1 drop/second) through a glass column (5-10mm in diameter) filled with 2g of Amberlite® IRA-400 strong-base ion exchanger. The solution must not contain more than 2000mg/l (ppm) of the interfering anion. Then test for Ca2+ as described in the directions. Standard (1000mg/l)19778 Calcium standard solution, 500ml. |
