There are enough reagents for 50 tests to be used with a compatible benchtop or portable photometer. These high quality reagents are clearly marked with the lot number and expiry date on each bottle and packet for traceability.\u003c\/p\u003e\u003cp\u003eThe HI-93748-01 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 manganese 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 μg\/L (ppb) of manganese. These reagents are designed to be used with samples that have an expected range of 0 to 300 μg\/L manganese.\u003c\/p\u003e \u003cp\u003eThis reagent provides enough to do 50 tests.\u003c\/p\u003e \u003cp\u003eRange: 0 to 300 ug\/L\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.
