FAQs
Can I use AR grade methanol for HPLC?
Sometimes, for isocratic methods at longer wavelengths, but AR grade is not tested for UV absorbance or gradient blanks. For low-wavelength or gradient work, HPLC grade avoids baseline and ghost-peak problems.
Is HPLC grade the same as gradient grade?
Gradient grade is a subset of HPLC grade that has additionally been run as a blank gradient to show no interfering peaks. It is preferred for gradient methods and trace analysis.
Is HPLC grade suitable for LC-MS?
It may work, but LC-MS grade is recommended because it limits metal ions and background contaminants that cause adducts and ion suppression.
