Sample Measurement

Quick Help

Most issues concerning accuracy and reproducibility are sample or measurement technique related and are resolved by following the suggestions below:

  • Ensure that the sample isolation procedure is optimized and samples are purified prior to making absorbance measurements.
  • Ensure all solutions are homogenous and well-mixed prior to sampling.
  • Ensure sample concentrations fall within the linear range of the instrument.
  • Establish a new blank using the appropriate buffer.
  • Verify that the buffer does not have significance absorbance at the analysis wavelength.
