水中总有机碳（TOC）是评价水质的重要分析参数。总有机碳浓度的测量在各种工业和环境应用中起着关键作用。本文介绍了一种新的TOC分析仪，它被设计成一种易于使用、可靠、高性能的仪器，以满足工业和环境用户的需求。Phoenix 8000是一款基于PC的紫外线/过硫酸盐分析仪，已在各种浓度水平上进行了准确度和精密度测试。已经证明，在低十亿分之一的范围内具有卓越的精度，以及将携带量降至最低的能力。

Total organic carbon (TOC) in water is an important analytical parameter in evaluating water quality. Measurement of total organic carbon concentration plays a critical role in a variety of industrial and environmental applications. This paper describes a new TOC analyzer that has been designed to be an easy to use, reliable, high performance instrument to satisfy the demands of industrial and environmental customers. The Phoenix 8000 is a PC-based UV/persulfate analyzer that has been tested for accuracy and precision across a wide range of concentration levels. Excellent precision at low parts per billion ranges, along with the ability to minimize carryover have been demonstrated.
