HEL?s PAT-IR mid-infrared spectrometer is a durable and compact unit, that can be fiber-optically coupled to measure chemical reactions in the laboratory and/or process environments. Features Include: -Non-destructive analysis in seconds -Ideal for in-line process measurements -Built-in 6-port multiplexer -Multiple components per measurement The PAT-IR is a process-ready FT-IR spectrometer that is ideal for real-time monitoring and analysis of chemical and biological reactions. The PAT-IR design protects the optics in a dedicated, sealed compartment. The PAT-IR is designed for a process environment, its small footprint can also make it ideal for laboratory-based applications.

HEL's motto is better chemistry - faster; our products are designed to enable research chemists to achieve their goals faster, more accurately and more efficiently. Operating internationally, HEL is a company that specialises in research and pre-pilot scale chemical reactors and systems. We provide both automated and manual tools for process R&amp;D to clients in the pharmaceutical, fine chemical and petrochemical industries, as well as in academia. Originally established in 1987 purely as a consultancy, the company has grown to include a complete team of chemists and chemical engineers, working from our fully equipped testing facility in the UK. Innovation and new product development through process screening are ingrained in HEL's culture, and our specialist software development team with now over 20 years' of automation and control experience, is continually improving the most powerful and chemist friendly software available. Qualified employees, modern production procedures, and chemical process equipment and technologies, as well as quality control, are the basis for our outstanding products and services. HEL'S PRODUCTS & SYSTEMS: Products According to Research Stage Whilst our traditional customer base is in synthetic chemistry, our products are suited to med-chem groups, bio processes and emerging technologies (such as alternative fuels, for example), as well as university research. HEL's product range broadly fits the following key stages of process development, and both high and low pressure designs are available for each phase: Screening... manual or with relatively simple controls Optimisation... using automated tools to perfect the process prior to scale-up with confidence, due to excellent data logging and control Scale up... bench and kilo laboratory reactors for safe scale up Products According to Specialisation HYDROGENATION & CATALYSIS TOOLS and reactions at elevated pressure form a significant portion of applications covered by HEL products. This is based on our strong chemical engineering background. CRYSTALLISATION AND PARTICLE CHARACTERISATION are especially important in the pharmaceutical and related industries, with several products in our portfolio. PARALLEL PROCESS DEVELOPMENT platforms, which can be adapted for different applications, form the backbone of many solutions in totally unrelated industries. SAFETY & CALORIMETRY have been our core strength since inception more than 20 years ago, and HEL still offers the widest range of products covering each step in the process development life cycle. BENCH & KILO SCALE REACTOR SYSTEMS based on our flexible and expandable AutoLAB system, backed-up by over 20 years in reactor design. BIO-REACTORS & FERMENTERS both single and multiple (parallel) bio-reactors for bacteria and cell applications. Customised Solutions Our modular chemistry platforms, designed by chemists and chemical engineers and supported by in-house mechanical, software and electronics engineering capabilities, allow us to offer cost effective systems with maximum flexibility.
