Advantages of Vacuum Distillation

http://www.vacuumdistillation.biz/advantages_of_vacuum_distillation.html

ADVANTAGES OF VACUUM DISTILLATION. INTERNAL STANDARDS FOR METHOD 8261. OVER PURGE and TRAP / HEADSPACE and THERMAL DESORPTION TECHNIQUES. The highlight and basis of the method is that. It provides a procedure that corrects the raw data for matrix effects and provides associated error criteria for each and every analyte detected. Biggest drawback of these techniques is that they cannot provide matrix correction of the data, in spite of all the “method modifications” developed over thirty years. These tech...
