Quality Assurance Procedures for the Analysis of Photosynthetic Pigments (GOFS-Level 2)

对光合色素浓度的可靠分析测量对于众多中尺度海洋计划(JGOFS、GOFS、WOCE、NASA等)的成功至关重要。对于这些多研究者、多年计划，必须建立标准和/或最低精密度、准确度和代表性指南，以避免获得有偏见、无意义或不可靠的结果。任何在很长一段时间内和/或从许多不同实验室获取数据的程序都需要一种机制，以确保正在获取的数据库的完整性和连续性。这里描述的活动是第一次尝试建立指导方针，并为光合色素测量设定现实和有意义的精确度、准确性和代表性目标。根据GOFS/JGOFS规划报告中概述的建议，这项研究将(1)制定和实施高效液相分析植物色素的质量保证计划；(2)为参与GOFS/JGOFS(和相关)计划的实验室提供外部和内部色素标准；以及(3)协调参加GOFS/JGOFS方案的实验室之间的相互校准工作。

Reliable analytical measurement of photosynthetic pigment concentrations is crucial to the success of numerous mesoscale oceanographic programs (JGOFS, GOFS, WOCE, NASA, etc.). For these multi-investigator, multi-year programs standard and/or minimum precision, accuracy, and representativeness guidelines must be established to avoid the acquisition of biased, meaningless or unreliable results. Any program that acquires data over long periods of time and/or from many different laboratories needs a mechanism to insure the integrity and continuity of the data base that is being acquired. The activities described here are a first attempt to establish guidelines and set realistic and meaningful precision, accuracy and representativeness goals for photosynthetic pigment measurements. Based on the recommendations outlined in the GOFS/JGOFS planning reports, this study will (1) develop and implement a quality assurance program for the analysis of plant pigments by HPLC; (2) provide external and internal pigment standards to laboratories participating in the GOFS/JGOFS (and related) programs; and (3) coordinate intercalibration exercises among laboratories participating in the GOFS/JGOFS programs.
