Can mobile phase(for HPLC) be keep for 1 day before use? Will that affects the accuracy of result produced?
I had prepared mobile phase A (consists of sodium acetate trihydrate add with acetic acid glacial and also triethylamide), mobile phase B (100% acetonitrile) and mobile phase C (deionized water) this morning. Can I use these mobile phase the next day when running the HPLC (high performance liquid chromatogarphy) ? Does this condition (prepared early mobile phase) affect the accuracy of the result produced?
I heard that the mobile phase need to be prepared freshly before used, for example 3hours before used, is that necessary? I need to perform analysis using HPLC for my school project. And I need the answer from someone here... HELP!!!
Depends on:
a) what the mobile phase is
b) how accurate you need results to be
c) whether you will do a system suitability test (using a standard)
We used mobile phase (depending on what it is) after several months.
