# Sample Dilution Accessories

## CHEMetrics Dilution Technology

Sample dilution can be used to extend the range of the kits and to mitigate interferences or sample discolouration or turbidity. Dilution must be preformed accurately to minimise the introduction of errors. Sample dilution is also not appropriate for all analytes, for instance, alkalinity, carbon dioxide, conductivity, dissolved oxygen, pH and ozone.

CHEMetrics offers a variety of test kits in different ranges to suit the majority of requirements, including HR CHEMets Visual Test Kits which utilise precise aliquot sampling technique for use with concentrated samples including including MiniPets® and/or syringes. CHEMetrics also offers a wide range of dilution accessories for use with selected kits, including MiniPets®, syringes and sample cups.

For more information on general considerations for dilution, please see our FAQs page.

## MiniPets® & Syringes

This is our recommended dilution method. Dispense the specified volume of sample into the appropriate sample cup using either MiniPet® or syringe and dilute to the specified total volume with distilled water. Then use this diluted solution in conjunction with the normal procedure for the test kit you are using, e.g. Chlorine. Take the result from this test and multiply it by the appropriate multiplication factor below, yielding the actual concentration value for the original undiluted sample.

If you are using the MiniPet® to dispense the sample, first place the yellow pipette tip (A-0171) firmly onto the end of the appropriate MiniPet® [1]. Then depress the plunger on the MiniPet. Immerse the yellow tip in the water sample and release the plunger. This will draw the sample into yellow tip [2]. Hold the MiniPet® over the selected sample cup and depress the plunger to dispense the sample [3].
