In-line liquid and gas color, concentration (UV-VIS-NIR) & turbidity analyser - Robust industrial DIN Flange, TriClamp, ATEX, Optic fiber

If either a liquid or gas has an absorbance between 250nm and 2000nm, then a Kemtrak photometer can measure it. Kemtrak photometers and turbidity meters use a long life high performance LED light source with robust industrial grade fiber optics to provide drift and noise-free measurement with very high precision.

Kemtrak offers a comprehensive range of measurement cell manifolds that can withstand the most harsh of industrial environments. High temperatures, pressures and explosive environments (ATEX) are available.

Process color measurements of liquids are a vital part of many operations where precise process control and high product quality standards are desired.

Color measurements are commonly used for number of reasons, including:

  • color addition control
  • color removal control - optimize filtration or ion beds used to strip color
  • color avoidance - leak detection, yellowness caused from overheating or charring, contamination detection
  • dilution and dosing control
  • quality assurance & control

Some common color scales used in the chemistry industry include:

Hazen (APHA) is a measure of yellowness originally designed to evaluate the color of near-colorless waste waters by visual comparison with a platinum-cobalt (PtCo) stock solution.

Hazen, platinum cobalt, Pt/Co, Apha  drinking water colour Hazen Color Applicaiton Note


Iodine color ranges from yellow to brown defined by specified dilutions of an iodine solution.  Used for solvents, plastics, resins, oils and fatty acids.  

Saybolt (ASTM) covers the determination of the color of refined oils such as undyed motor and aviation gasoline, jet propulsion fuels, naphthas and kerosene, and in addition, petroleum waxes and pharmaceutical white oils.

 

In-line liquid and gas color, concentration (UV-VIS-NIR) and turbidity measurement - Kemtrak industrial process fiber optic photometers


The Kemtrak DCP007 LED process photometer with in-line measurement cell can instantly detect minute changes in color that is beyond the sensitivity of the human eye and will furthermore eliminate operator interpretation errors.

The Kemtrak DCP007 uses a proprietary dual wavelength four channel measurement technique and advanced digital electronics design to provide deep absorbance measurement to 5 AU using a 1cm optical path-length. A range of shorter optical pathlengths allow for deeper absorbance measurements. Automatic compensation for sample turbidity and/or fouling of the optical windows ensures trouble free operation. The resulting measurements are very accurate with low drift and long-term calibration stability.


If two phases have a difference in either turbidity or absorbance between 250nm and 2000nm, then they can be accurately monitored using a Kemtrak process photometer. By monitoring at strategic points in the process, immediate detection of product-product or product-water interfaces can be achieved.

The benefits include:

  • reduced product loss
  • increased product quality
  • faster product changeover
  • reduced waste water contamination

The net benefit is a substantial cost reduction.

Kemtrak photometers are easy to install and require no maintenance. Use a Kemtrak DCP007 LED process photometer for monitoring changes in color or a Kemtrak DCP007-NIR LED process photometer for detecting variation in the water or organic content between the phases.

Wherever a second fluid is used to heat or cool a process, a risk of product leakage or carryover exists. Leak detection in process equipment such as heat exchangers and boilers are a vital part of safeguarding a chemical process. Immediate detection of leakage or carryover can be achieved by installing a Kemtrak photometer on the condensate line.  

Benefits include:

  • equipment protection (filters, boilers etc)
  • product, process and environmental protection
  • reduced downtime
  • increased water re-usage - condensate can be used for CIP pre-rinse and boiler feed

From a continuous monitoring of the process water for signs of contamination, conservation of water, energy and treatment chemicals is the result. The net benefit is a reduction in operating costs.

The monitoring of changes in color or UV absorbance in the condensate is a reliable means of detecting leaks. Such measurements can detect trace levels of contamination allowing repairs to be scheduled before a catastrophic breakdown occurs.

The Kemtrak DCP007 LED process photometer uses robust industrial grade optic fibers to pipe the light from within the analyzer enclosure to the measurement point and back. This is a major benefit as all the electricity is kept within the analyzer enclosure permitting safe operation in even the most hazardous of environments.

A comprehensive range of both standard and custom designed industrial measurement cells are available to suit virtually any application. Contact a Kemtrak sales representative for more information.


The measurement of water in alcohol or hydrocarbon solvents is an important measurement in many industrial processes. Water can be accurately monitored in a wide range of samples from trace quantities to 100% using a Kemtrak photometric process analyzer. A Kemtrak water analyzer is a recommended replacement for inconvenient and expensive Karl Fischer titration analyzers. Benefits include no maintenance, no reagents and continuous results in real time.

Water measurements can be undertaken on hydrocarbon solvents with ppm accuracy. Proven applications include acetone, isopropyl benzene, propane, tetrahydrofuran, methyl-isobutyl ketone in addition to fuels such as petroleum and aviation gasoline. Additionally, water can be measured in alcohols, such as methanol and ethanol, from trace amount to pure water.

Water has two regions of activity in the NIR region between 1000 - 2000nm. At 1400nm the O-H stretch in the water molecule is measured, while at 1900nm water has a unique peak due to a combination of O-H stretch and
H-O-H bending. The water peak at 1900 is about five times as large as the water peak at 1400.
