Классификация USP L ВЭЖХ колонок Agilent Technologies
| The US Pharmacopeia (USP) is a standard source for many pharmaceutical methods. The USP specifies columns by packing materials rather than by manufacturer. The USP has updated its L1 definitions, listed below you will see the most recent definitions and columns that apply. Rapid Resolution High Throughput (RRHT) columns are now choices in the L1, L7, and L11 categories. |

Goals of Sample Preparation
Successful sample preparation for most analytical techniques (HPLC, UPLC, ™LC-MS, UV, GC, etc.)
has a threefold objective. It needs to provide the sample component of interest:
■■ In solution
■■ Free from interfering matrix elements
■■ At a concentration appropriate for detection or measurement
Waters™ Sample Preparation Solutions for quantitative analysis make it easy to deliver a sample that is reproducible with
high recovery and free of interferences. Based on simple, logical workflows that produce clean samples through selective
separations, Waters Sample Preparation Products maximize sensitivity, increase throughput, and enable the development of
robust methods.
