| Remarks | pH meters are used to access the alkalinity and / or acidity of fluids in a variety of laboratory procedures. These include: - Ensuring that aqueous reagents or buffers are prepared at the correct pH for various “in-house” tests including LCMS procedures. - Testing urine samples for adequate acidity / alkalinity prior to analysis of urinary analytes such as calcium, magnesium and urate. To assess these general laboratory applications, aqueous EQA material with a pH covering a wide range of pH from 2 to 12 is used. Three liquid stable samples are distributed monthly with a minimum of 36 samples distributed over the year covering a wide analytical and clinically relevant range. The samples consist of a panel of 12 samples, each distributed on 3 occasions over that period. This allows for the assessment of laboratory and method performance, including linearity, bias, within and between batch imprecision. Key Features: - Samples are supplied ready to use; no pre-analytical preparation required. - Suitable for assessing pH Meter performance across a number of laboratory applications. - Wide range covered. - Multiple panels distributed on a number of occasions over the year. - Stable material.
