These high-quality reagents are clearly marked with the lot number and expiry date on each packet for traceability.\u003c\/p\u003e\u003cp\u003eThe HI-753-25 are high-quality reagents that are pre-measured, allowing for users to achieve fast and accurate measurements with their Chloride Checker® HC. These reagents follow the Mercury (II) Thiocyanate Method in which the reaction between chloride and the reagents causes an orange tint in the sample. By simply adding the two reagents from the HI-753-25 set, the reaction will take place and the HI-753 will determine the concentration from the colour that is produced. The results will be displayed in ppm of chloride. These reagents are designed to be used with samples that have an expected range of 0.0 to 20.0 ppm chloride.\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\u003eWhenever 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\u003eFour steps.
