Why are absorbance values higher than expected on my biochrom Libra S70 Measuring Instruments?
Elevated absorbance readings can stem from several factors: * Verify you're using the correct cell type. * Ensure cells are free from fingerprints and contamination. * Confirm correct cell orientation. * Verify the reference used.
What to do if absorbance value is lower than expected in Biochrom Measuring Instruments?
If you observe lower than expected absorbance values, consider the following checks: * Ensure sufficient height of sample solution. * Verify that the sample and reference are not the same. * Make sure the sample compartment lid is properly closed.
How to fix negative absorbance reading on Biochrom Measuring Instruments?
To resolve a negative absorbance reading, check that the sample and reference cells have not been swapped. Also, ensure there is sufficient height of sample solution. The beam height is nominally 15 mm above the cell base for normal measurements, and it is recommended that the solution be filled to 20 mm above the base.
How to improve poor reproducibility in nucleic acid analysis using biochrom Libra S70?
To improve reproducibility in nucleic acid analysis, check for any particles in the solution and consider using background correction. Also, try increasing the concentration of the sample.
What to check if Biochrom Measuring Instruments will not reference?
If the instrument won't reference, check the orientation of the cuvette and verify that you are using the correct cell type.
