The Insitec LPS can be used off-, at-, in- or on-line for a very wide range of processes. Each component of the system – sampler, pre-diluter, cascade diluter, measurement cell, and software – can be individually tailored to the process, ensuring that even the most challenging applications can be tackled effectively. The Insitec LPS sampler extracts 2.5 ml liquid slugs from the full pipe section. There is never any cessation of sample flow, thus avoiding blockages. The process interface is designed for high pressure (where necessary) and for easy installation and maintenance. The pre-diluter and cascade diluter work together to bring the sample to an optimal concentration for analysis while avoiding dilution shock. These components have few moving parts, are self-cleaning and are designed to minimize diluent consumption. Consistent dilution is achieved efficiently with no manual intervention.
