The Millipore® Fluid Sampling Kit is used for direct fluid sample collection prior to contamination analysis. Compatible with the collection of turbine fuels, water or other liquids, samples are collected from quick-release valves installed in the system line with a portable stainless-steel sampler assembly. After drying and removal from the sampler assembly, the resulting sample can be used in gravimetric or colorimetric analysis.
The Millicup™-FLEX filter unit provides a disposable and time saving alternative to traditional glass vacuum filtration systems. The filter unit consists of a fully recyclable polypropylene funnel and a recyclable ribbed membrane support collar suitable for most filtration applications. Its unique construction enables faster flow rates compared to glass.
The Millipore® Patch Test Kit is a complete solution for the field-based collection and analysis of hydrocarbon-based hydraulic fluids, hydraulic oils, bulk chemicals, boiler water, and lubricating oils. This portable system allows for the dependable detection of contamination through sensitive, colorimetric analysis.
Millipore® 47 mm stainless-steel aerosol filter holders were designed for sampling large particle volumes, such as those found in a dust-containing environment requiring protective clothing. These reusable filter holders utilize 47 mm filters and are available in two different configurations. The open-face configuration allows for maximum, unimpeded flow during sampling, while the closed-face configuration allows for optimum particle distribution on the filter.
Depending on the particle of interest and environment, different sampling methods, air monitors, and membrane materials are used. Millipore® monitoring devices (37 mm and 25 mm) and membranes are designed for use in variety of standard testing methods, including those from NIOSH, ASTM™, EPA, or OSHA™.
High performance liquid chromatography (HPLC) can be used to separate and identify different large biomolecules such as protein and peptides in a sample. It is based on the pumping of a sample with a solvent (mobile phase) through a column packed with sorbent material (stationary phase) at a high pressure.
Small molecules are ions and compounds of molecular weight typically less than 900 daltons. These compounds can be effectively separated and analyzed by HPLC, UHPLC and LC-MS using mainly silica particles or monolithic stationary phases with a broad range of column chemistries (modifications).
Water treatment is required to maintain effluent compliance with standards established by regulatory bodies. Learn about the stages of wastewater and process water treatment along with the corresponding analytical testing methods.
Soil and groundwater testing are crucial to avoid adverse impact on the environment and human health. Learn about the importance of solid waste management and methods used for soil and groundwater testing for heavy metals and other environmental pollutants.
Filtration separates substances based on physical or chemical properties. Lab samples are routinely filtered before analysis to reduce sample complexity and increase analyte purity. This allows scientists to generate higher quality analytical results.
