There are enough reagents for 150 tests to be used with a compatible benchtop or portable photometer.\u003c\/p\u003e\u003cp\u003eThe HI-93740-03 are high quality reagents that are pre-measured, allowing for users to achieve fast and accurate colorimetric measurements. The method is an adaptation of the 1-(2-pyridylazo)-2-naphthol (PAN) method. The reaction between nickel and the reagents causes an orange tint in the sample. By simply adding the reagents to the sample, a reaction will take place and a compatible benchtop or portable meter can be used to determine the concentration from the colour that is produced. The results will be displayed in mg\/L (ppm) of nickel. These reagents are designed to be used with samples that have an expected range of 0.000 to 1.000 mg\/L nickel.\u003c\/p\u003e \u003ch3\u003eTip for an accurate measurement\u003c\/h3\u003e \u003cp\u003eIt is important that the sample does not contain any debris.\u003c\/p\u003e \u003cp\u003eWhen the cuvette is placed into the measurement cell, it must be dry outside and completely free of fingerprints, oil or dirt. Wipe it thoroughly with HI-731318 or a lint-free cloth prior to insertion.\u003c\/p\u003e \u003cp\u003eShaking the cuvette can generate bubbles, causing higher readings. To obtain accurate measurements, remove such bubbles by swirling or by gently tapping the cuvette.\u003c\/p\u003e \u003cp\u003eDo not let the reacted sample stand for too long after reagent is added, or accuracy will be lost.\u003c\/p\u003e \u003cp\u003eAfter the reading, it is important to discard the sample immediately, otherwise the glass might become permanently stained.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eReagents:\u003c\/td\u003e\n\u003ctd\u003e150 tests LR Nickel ISM - HI-93740\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage\u003c\/td\u003e\n\u003ctd\u003ePacket \u0026amp; bottles\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQuantity\u003c\/td\u003e\n\u003ctd\u003e150 tests\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMethod\u003c\/td\u003e\n\u003ctd\u003eAdaptation of the 1-(2-pyridylazo)-2-naphthol (PAN) method.
