New regulations require testing asphalt for PAHs. Sitelab's UVF-3100D and TD-500D analyzers can test asphalt quickly and accurately. Results takes less than 5 minutes. The equipment is easy to operate.
Advanced optics manufacturing is now requiring much cleaner processing environments than were necessary in the past. Smaller device structures, use of shorter wavelengths, and higher laser power densities are all factors that make advanced components more susceptible to damage from contamination. Particle Measuring Systems can provide you with the tools to determine how clean your environment is.
Mercaptans or THT are added to natural gas to make it smell and to make it detectable by the human nose (odorization process and odorization control in pipes).
energyMEDOR ppm: 30 years’ experience.The compounds usually used to odorize natural gas vary from one country to another but are usually:
Ter Buthyl Mercaptan (TBM)
Analyze H2S and mercaptans concentration in natural gas (ppm).
The vigi e-nose is an analyzer able to track VOCs, Sulfur compounds and other molecules such as ammonia for example. It allows to provide a rich global fingerprint to correlate with human sensory evaluation as dynamic olfactometry as example. It is possible to train the vigi e-nose with human sensory samples to study correlation with ASTM 679-E04 or EN 13725.
As electronic nose, it provides chemical and olfactive fingerprint.
The main differences are that vigi e-nose offers with single instrument :
The odor market usually asks a spot measurement using dynamic olfactometry. This method uses human nose to quantify odor as global fingerprint. Chromatotec has developed a new solution for continuous monitoring as a complementary solution to the human nose. The vigi e-nose analyzer allows to monitor sulfurs compounds with speciation in addition to total VOC and odor index. Correlation with human nose according to EN 13725 method are defined site per site.
Our MAC moisture analyzers can also assist in a number of applications for industry and manufacturing. Even if you are not working with an oven or concerned with monitoring flue gases, you may still find yourself in need of moisture monitoring capabilities, such as if your project concerns:
Sampling and analysis of fire effluents is an important part of assessing both the environmental impact and the threat to life caused by fires. Detailed knowledge about the composition and concentration of fire effluents is required to gain a good understanding about the potential impacts of fires and for efforts to diminish these impacts. Testing the composition of these fire effluents presents a challenge for the analytical equipment used to measure the gases. The amount of species and concentrations of...
Cargo containers and wooden packing materials are fumigated to control the spread of pests and micro-organisms. However, fumigant gases are toxic and present a danger to human health even at low concentrations. Additionally, products shipped in containers may release VOCs from the solvents, coatings and glues used in manufacturing processes, and the concentrations of these vapors may be significant in the confined space of the container. Gas measurements are required to protect the health of any workers involved...
Durable, reliable analysis for black liquor. Black liquor is a difficult substance to work with. It’s caustic, it’s toxic, and it emits poisonous gases such as hydrogen sulfide. But the efficient use of black liquor is critical to the profitable operation of any pulp and paper mill. In order to use black liquor efficiently, you need to test it for solids. Make sure your solids analyzer is up to the task.
The United States Environmental Protection Agency (EPA) has two stack testing methods for FTIR gas analyzers. Method 320 is an FTIR method for measuring wide range of organic and inorganic pollutants. Method 321 is a specific version for measuring hydrogen chloride HCl at cement kilns producing Portland cement. These methods define a quality assurance and control processes for verifying the accuracy of the results. The requirements for analytical equipment and software are defined on 40 CFR Part 60 Appendix B...
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...
Membrane units, in our days are widely used in the water pre-treatment preparation and are becoming one of the most important technologies in the production of high pure water. Nevertheless they often face problems with scaling and fouling and are therefore limited by frequent maintenance, downtime and high costs. Our treatment programs are specifically designed for membrane units like reverse osmosis, ultra- and nanofiltration and enable to remove or preventive control scaling and fouling. Our main target is to...
The ambient air in clean air rooms needs to be constantly monitored for the safety of workers and of the production according to the environment. A clean air room is a room where the concentration of particles is controlled in order to minimize the introduction, the generation, retention of particles inside, for instance for chip production or the production of medicines.
Most large coal fired power plants and combustion processes are required to monitor CO, NO and NO2 (NOx), SO2 and possibly CO2; in addition the analyser has to be normalised to Standard conditions. For this application CODEL offers the five channel GCEM 40 series which uses Infrared absorption to measure these gases plus moisture, pressure and temperature. The analyser can be configured for single channel operation to monitor any of these gases plus CH4 and HCl.
