Purge and Trap Background
When using a concentrator system, it is not essential to understand how it works. However, a good grasp of the fundamentals helps you prevent problems and assists you when you are faced with tasks such as method development and troubleshooting. This section is not intended to be a full theoretical evaluation of purge and trap gas chromatography. The main purpose is to help you develop an understanding of how and why compounds are concentrated.
This instrument is designed to be extremely accurate, fast, and simple to use in diverse water quality applications.
With an easily scalable solution the 182, 182 XT, and 182 XT-4 allow for the connection of 1-4 sensors depending on which terminal you choose. Add sensors at any time and at any location or change them out with ease.
The Series NXT3000 Gas Feed System is a family of vacuum-operated, solution-feed gas dispensing components including a vacuum regulator, meter assembly, and a selection of ejectors to meet customer needs for feeding chlorine, sulfur dioxide, ammonia or carbon dioxide gas. The Series NXT3000 is a versatile, high quality system which operates at sonic conditions eliminating the need for regulating differential pressure across the rate control valve. Proven design, rugged construction, and the use of the best available materials assures precise gas feeding, low maintenance and dependable operation for the life of the equipment.
The Aztec 600 Low Range Manganese Analyzer AW634 offers reliable and accurate on-line analysis of manganese up to 0.10 ppm Mn.
The Rosemount CX1100 In-Situ Oxygen Analyzer provides measurement of oxygen in clean-burning applications. Get accurate oxygen measurements to optimize combustion reactions, reduce energy costs and meet environmental regulations. All welded construction and no reference gas requirement reduces installation and maintenance costs.
The Signet 4150 Turbidimeter system provides accurate and reliable EPA-compliant water quality monitoring for municipal and industrial applications.
The AM-TBR was designed to be cost effective to purchase and even more cost effective to maintain. The turbidimeter is modular to make servicing and cleaning quick and easy. The compact sample volume of 30 ml means that you will go through less calibration solution over time.
The Fusion Total Organic Carbon (TOC) Analyzer utilizes UV Persulfate oxidation allowing superior carbon liberation from even the most challenging matrixes. Low-end sensitivity is achieved from a Non-Dispersive Infrared (NDIR) detector. The Fusion Total Organic Carbon (TOC) UV Persulfate Analyzer offers more flexibility, intelligence and user friendliness making this analyzer ideally suited for the most demanding laboratory needs.
