I am working on hydrophobic drug. DMSO is used as a solvent, when OD is taken it give me larger value. what is the best possible way to get appropriate value and nullify DMSO OD. Regards Nabeela Jabeen
To cut off the optical density (OD) values of DMSO in a sample, you can follow these steps:
Prepare a blank solution: Take a sample containing only the solvent (DMSO) without any other components. This blank solution will serve as a reference for the baseline OD reading.
Measure the OD: Using a spectrophotometer, measure the OD of the blank solution at the specific wavelength of interest. This will give you the baseline OD value for DMSO.
Subtract the blank OD: Take the OD readings of your sample containing DMSO along with other components. Subtract the OD value of the blank solution from each of the sample readings. This will help eliminate the contribution of DMSO to the overall OD value.
By subtracting the OD of the blank solution, you can effectively remove the influence of DMSO on the measured OD values in your sample. This allows you to focus on the specific effects of the other components present in your sample.
It's important to note that this method assumes that DMSO does not interfere with the measurement at the specific wavelength you are using. Additionally, make sure to validate and verify this approach for your specific experiment and instrument setup.
