Inline process refractometers and sensors can perform industrial measurements continuously, and in real time. This technology is also known as PAT (Process Analytical Technology), and here at Fullbrook Systems, we provide Schmidt & Haensch’s leading range of inline refractometers that allow you to monitor and control your processes without product loss or process divergence. With Schmidt & Haensch’s process refractometers, quality control and the determination of liquid concentration and mixing ratios becomes simple. Measurements are always reliable and independent of turbidity, colour, absorption, and viscosity. This ensures the highest precision and improved process control. How does Process Analytical Technology work? Process Analytical Technology (PAT) is a manufacturing methodology for high value chemicals and pharmaceuticals. Critical Process Parameters (CPPs) and Key Performance Indicators (KPIs) of the process are comprehended, well-defined and continually monitored to ensure that the pre-defined Critical Quality Attributes (CQA) of the final product are consistently achieved. PAT measures key quality and performance indicators in both raw and in-process materials in real-time. A well-designed PAT-based process is stable, ensuring that the critical parameters and indicators remain within pre-described limits to safeguard product quality and process safety. What instruments does the range include and what are their benefits? The current range of Schmidt & Haensch inline refractometers include:
 Which industries can these refractometers be applied to?
The refractometers from Schmidt & Haensch can be used in the following industries:

If your research and production require accurate measurement of light scattering components, both in-line and in real time, then the Kemtrak Inline Turbidity Meter offers an ideal solution. This easy-to-use industrial process fibre optic turbidimeter contains long-life solid state LED lamps and precision fibre optics to provide drift and noise-free measurement at extremely high precision. Hassle free operation is ensured by automatic compensation of sample colour and fouling of the optical windows. The scratch resistant sapphire windows have no electronics or moving parts, making the unit appropriate for use in hazardous areas, as well as making them maintenance free. Other benefits of this popular piece of kit from Kemtrak include: • ISO 7027:1999(E) compliant • Reliable and robust infrared LED lamp • Extensive range of robust fibre optic measurement cells • Analogue output (0/4-20 mA) • Local and web based graphical user interface (TCP/IP). How does the Kemtrak Turbidity Meter work? The turbidity meter is made up of a control unit, flow cell and fibre optics, and is designed to measure the lack of clarity or “cloudiness” of a fluid caused by undissolved particles. Modern turbidimeters use a technique called nephelometry, which measures the amount of light scattered at right angles to an incident light beam. Both transmitted light and scattered light at 90° is measured and mathematically combined using a ratio algorithm to calculate the turbidity of the sample. The dual detection system and ratio algorithm then provides a turbidity measurement that has significantly better performance with coloured and/or light absorbing samples. A long-life LED light source is used to produce reliable turbidity measurements from 0.01 to over 4 000 NTU depending upon the configuration of the optical measurement cell or probe. This means the Kemtrak TC007 is an instrument of high accuracy with long-term calibration stability. What applications is the Kemtrak Turbidity Meter normally used for? The Kemtrak is typically applied in: • Filtration monitoring • Centrifuge control • Interface detection • Phase separation • Leak detection • Oil in water • Quality control To find out more about how this technology can benefit your research, production, or development, get in touch by calling: 01442 876777, or email us at: [email protected].  The Kemtrak FL007 is a fibre optic probe-based oil in water monitor that is ideal for those looking to: • Trace oil in water • Detect leaks • Measure cooling water and condensate return • Monitor drinking water, wastewater, and impact on the environment. Offering a state-of-the-art combined fluorescence and turbidity measurement, the Kemtrak FL007 provides reliable, continuous monitoring of oil and hydrocarbon contamination in water. Highlights include: • Simultaneous UV fluorescence and turbidity • Hygienic Ø12 mm PG 13.5 immersion probe • Real time in-line measurement • Calibration for 16 different oil types • Suitable for hazardous area use • Alarm, 4-20mA and Modbus communications. The probe works on the basis that mineral oils rich in aromatic content will fluoresce when illuminated with ultraviolet light. The intensity of this fluorescence is dependent upon the polyaromatic hydrocarbon (PAH) content of the oil. Typical oils that fluoresce are fuel oil, crude oil, hydraulic oil, and transformer oil. Every oil has its own unique fluorescence intensity, resulting from its specific PAH content. The combined fluorescence from both dissolved and dispersed oil in water can then be measured and correlated to the oil content. Other gases and solids present in the stream will not fluoresce and therefore do not affect the measurement, and it’s important to bear in mind that non-mineral oils or hydrocarbons low in aromatic content may not fluoresce. Standard features of the Kemtrak FL007 include: • 16 linearization tables for multiple product switching • Remote zeroing • Automatic cleaning cycle • Signal filtering. A range of standard fittings and retractable probe holders to be used, due to the immersion probe having the same dimensions as industry standard Ø12 mm PG 13.5 pH sensors. If you’re working in a hazardous environment, the probe is still suitable for use owing to its robust, industrial fibre optic probe with scratch resistant sapphire optics, no electronics, and no moving parts. It can also be remotely operated and calibrated through a built-in graphical internet-based interface using a standard web browser.
