necessary) to get all the sediment back into suspension. 2. Fill the tube to about 40 mL with DI water, shake or vortex well, and repeat the centrifuge/sip/rinse procedure twice more. 3. Move on to the next pretreatment, refrigerate the sample for future analysis, or prepare the sample for grain size analysis 5. Be sure to clean the centrifuge when done.
Since most samples encountered in a chromatography laboratory are not in a form to be directly placed into the analytical instrument, some form of preparation is required for nearly every sample. The sample preparation could be as simple as "dilute and shoot" or as complex as multistage sample handling.
