Moisture needs to be measured in feed stock gases in the manufacture of polymers . For example, pre-dried benzene is fed in to a reactor containing hydrochloric acid – if the dryers are not operating properly moisture in the benzene promotes acid corrosion of the reactor and process lines. Several processes require water concentrations of specific values to optimise efficiency and yield; in such cases more sophisticated instruments are required.
The chloride process of titanium dioxide (TiO2) pigment manufacture first converts titania-containing ores to TiCl4 via a carbochlorination reaction at a high temperature in a chlorinator in the presence of chlorine gas and petroleum coke added as a reductant.
Accurate liquid flow sensor measurement can reduce water bills, determine leakage rates, and increase system efficiency. Solve accurate water and industrial liquid flow measurement requirements with clamp-on or insertion ultrasonic flow liquid flow meters featuring precision sensing elements or our complete line of multivariable mass vortex meters.
From the environmental point of view, an issue is any solid, liquid or gaseous substance introduced into the atmosphere that can cause air pollution. Given the wide variety of substances present in the atmosphere, have been proposed several methods of classification: Primary pollutants can be of gaseous or particulate.
We propose our product as a new powerful base for optical absorption analysis. One of the greatest advantages of this method is that virtually any sample in virtually any state may be studied. Liquids, gases, films, powders, surfaces can all be examined with a proper choice of sampling technique. Using LED-PD optopairs for mid-infrared spectral range allows developing portable sensors with high reliability and adequate accuracy that can be successfully applied in different areas for matter analysis purposes.
IR-Spectroscopy is not limited to gases, solid materials and pure liquids but also facilitates the measurement of solutes in aqueous media. Though, due to the strong and temperature dependent absorption of water, the usage of conventional IR-transmission and ATR accessories is not very suitable for the analysis in water. The CONFOCHECK is a dedicated FT-IR system for the fast, easy and sensitive analysis of aqueous samples. Using this system, preparing, measuring and evaluating any aqueous sample takes typically...
Everyone has a responsibility to care for the environment to reduce the levels of pollution, including businesses that daily release emissions into the air and the ground. This is why we provide a full-service environmental testing service to help businesses identify problems and resolve them so they operate in the most environmentally-friendly method possible. We offer air emission testing, emissions monitoring services and stack emissions testing to businesses of all sizes.
Manufacturing of powdered and liquid flavorings and fragrances involves production phases where flavoring chemicals may be released into the ambient air breathed by workers. Exposure control by gas analyzers in the production rooms and laboratories is necessary to ensure that the Time-Weighted Average (TWA) concentrations do not exceed the maximum Permissible Emission Limit (PEL) values.
Evaporative gas cooling and conditioning systems help protect your downstream equipment, enhance air pollution control performance, reduce gas volumes, and increase production capacity. Central to our systems are Turbotak atomizing nozzles, which introduce a controlled amount of finely atomized water into the hot gas stream to reduce and/or maintain gas temperature. The water evaporates, while absorbing heat from the gases, for free-flowing dust, zero liquid discharge, and minimal or no wall buildup.
For the manufacturers of edible oils it is very important to control the crushing process at all the stages to achieve the best cost efficiency. In order to provide maximum yield and meet the product specifications it is necessary to monitor process as closely and rapidly as possible. Rapid determination of the key parameters with the use of InfraLUM® NIR analyzers provides the opportunity to control the process at every stage from quality control of oilseeds at intake point to the QC of the final product...
Our single ion and multi ion kits allow for real-time laboratory analysis of one to six ions simultaneously with one probe. These ion sensors along with the reference electrode are solid state which allows for easy handling, storage and maintenance. No filling solutions nor buffers are required. The sensors are based on carbon nanotube technology allowing for reliable and reproducible measurement of ions in liquids.

The Adsorbent Tube Injector System (ATIS) was developed at Supelco® by R&D Scientists, as a tool to assist in our comprehensive adsorbent research for thermal desorption tubes. The ATIS provides an efficient means of transferring calibration standards in either the gas or liquid phase onto the adsorbent packed tubes.
The ATIS employs the technique of flash vaporization to vaporize the sample in a continuous flow of inert gas; the inert gas carries the sample to the tube. The sample pathway of the ATIS is construct...
Most chemical reactions are based on direct mass flow readings, and thus, Sierra`s immersible thermal mass flow meters and our volumetric vortex and multivariable mass vortex flow meters see extensive used in oil, gas and steam measurement. In addition, process liquid flows can be addressed with our non-intrusive clamp-on ultrasonic flow meters. Finally, our capillary thermal mass flow meters and controllers are perfect for semiconductor processing applications.
The exhaust gas from combustion engines is a complex mixture of gases and particulate matter. The composition of the gas may change rapidly. Multicomponent analysis of exhaust gases can be performed with a Gasmet™ FTIR Gas Analyzer with a response time (T90) of one second. The winning combination is the result using of a small volume gas sample cell, a powerful sample pump and a fast detector with liquid nitrogen cooling. The analyzer, sampling system and computer can be assembled on a cart for use in a...
Thermal mass flow meters provide excellent measurement capabilities in dry gas flows. They have proven durability, accuracy, and repeatability. However, thermal flow meters are sensitive to liquid droplets in a wet gas stream. For a thermal flow meter to work accurately in a condensing gas environment, the probe must be placed far enough downstream so that the entrained water has condensed onto the pipe wall. In a very wet environment, any condensing liquid (commonly referred to as mist or fog) contacting the...
Spire Metering offers several solutions for leakage detection. The flowmeters are used to monitor cooling water in machining process. They are used also in liquid process control and leakage detection applications.
