Question
At about what concentrations are the Chlorine Mid-Range SpecCheck Gel Secondary Standards?
Summary
Secondary standard concentrations.
Answer
Below are the approximate standard concentrations for the three standards included in SpecCheck Secondary Gel Standards Set, DPD Chlorine - MR (Product # 2980500):
Standard 1 is ~0.18 mg/L
Standard 2 is ~1.50 mg/L
Standard 3 is ~2.70 mg/L

The actual expected concentration for each standard will be specific to that lot of standard and what instrument the check is being done on. Please review the Certificate of Analysis that is included with the standard to get the actual expected result for each standard on the instrument that is being tested as well as the acceptable tolerance.
