Advanced Sampling Process Instruments Ltd (ASPI) is a Scottish company that focuses on the design, development, manufacture, supply and support of specialist instruments and algorithms for aqueous (water) process control systems.

Founded in 2014, ASPI’s instruments include a unique patented In-process Liquid Sampler (ILS) that provides a stabilised process sample which can analyse hostile and turbulent aqueous processes. Designed to reduce complexity, ILS is particularly effective in its ability to operate in-situ measurements free from any maintenance for long periods and its sample capture method significantly minimises moving parts, increasing durability and reliability.

ILS has applications in many aqueous processes where in-situ analysis is beneficial including Biological Wastewater treatment analysis, Oil & Gas and Distilling and Brewing.
