Used DIONEX VWD-3400 #9084926 for sale

DIONEX VWD-3400 is a state-of-the-art technology lab equipment designed for the detection of total organic carbon (TOC) and volatile organic compounds (VOCs) in water. The device provides fast and accurate measurements with its high-sensitivity detector for a wide range of water quality parameters. VWD-3400 utilizes the principle of thermal desorption (TD) to detect organic compounds from a sample of water. The TD process consists of introducing the sample into an inert gas stream, followed by rapid heating of the latter in order to thermally volatilize the organic compounds from the liquid water sample. These volatilized compounds are then transported to a detection cell and sensitized, and their concentrations are then detected. The TD process requires a small amount of the sample with a reasonable sample volume that can be used for the measurements. To capture volatilized compounds, DIONEX VWD-3400 employs a 2-stage micro-channel plate (MCP) able to generate an electrical signal in response to the organic compounds. The MCP is equipped with a silica-based detector, offering high sensitivity and low detection limits of VOCs and TOCs. Moreover, the device features an autostripper process that eliminates the need for manual reagent replacement, significantly improving the sensitivity and accuracy of the results. The device is also equipped with an intuitive software system, DIONEX IDS-2K platform, that allows the user to manage and interpret the acquired data. This software system offers a range of options such as data acquisition, editing, data review, and data archiving. VWD-3400 is capable of operation in a wide range of environmental conditions, including those with high humidity and temperature variations. It also operates without the need of any external power, provided the sample is drawn at constant temperature and pressure. Lastly, the device is completely portable, having a compact size and light weight. This makes DIONEX VWD-3400 ideal for use in a wide range of applications, including research labs, industrial sites, and monitoring sites.
