PRODUCT HIGHLIGHT PT-AQ-02H - Nutrients and Others - Hard Water

PT-AQ-02H contains a suite of 7 spikes, a pH sample, and a hard surface water matrix: perfect for the environmental industry. The testing analytes also characterise the water and are important for assessing, amongst other things, the potential for eutrophication. Analytical problems can vary with the hardness of the water sample which is why the AQUACHECK PT Scheme offers both hard and soft water samples. Customers can select either water type (hard or soft) and matrices (raw or treated waters). There are approximately 150 participants per round. Due to the popularity of this sample, we have introduced a new sample PT-AQ-02HP, specific to potable water. 5 Rounds per Year
