Thermodynamics cannot yield any information about the intermediate states of a given reacting system. These intermediate states are the subject matter of chemical kinetics, which studies reaction rates and mechanisms. Chemical kinetics will predict what chemicals are present while thermodynamics…
One of the largest costs of monitoring gas levels is the ongoing cost of sensor calibration. The TR250Z Oxygen Sensor and O2/CO2 Combination Sensor are both designed to be calibrated in situ with the push of a button using normal…
Level measurement and control in process vessels can be one of the most challenging applications in which to obtain consistently safe and reliable results. Part of this difficulty may be due to the fact that the sizing of the vessel…
The pursuit of manufacturing excellence is a strong theme across all of the chemical process industries (CPI). Improving operations by eliminating variability and waste, a cornerstone of the six sigma approach, is essential for competitive performance in the global marketplace.…
Last month, this company launched a new range of SOLA solid-phase extraction (SPE) cartridges and plates. SOLA combines polyethylene frit materials and stationary phase components into one, uniform entity. As a result, these cartridges and plates deliver “superior” reproducibility, recovery…
The NEP-TX Series of molten-metal ceramic-sheath thermocouples (photo) features a 1,250°C temperature rating, connection head with terminal block and corrosion resistance. Standard construction includes a cast iron NEP-TX connection head and a 1 1/4 NPT fitting. Custom probe lengths are…
ReactIR 247 (photo) is a process-hardened Fourier transform infrared (FTIR) spectrometer designed to fit into nearly any space without sacrificing performance. Designed for classified environments, the instrument is engineered to be simple to operate, highly compact, cost effective and have…
The new wSeries Wi-Fi transmitter communicates on a standard Wi-Fi network, which is an economical solution for facilities with an existing Wi-Fi network as well as for new installations. Transmitters are available for analog voltage (0–10 V) and current (4–20…
A digital pressure gage combines the accuracy of digital technology with the simplicity of an analog pressure-measuring device. Given its very high sampling rate of 100 measurements per second, the CPG500 digital pressure gage (photo) is able to capture fast…
Version 8 of the Simatic PCS 7 process-control system boasts a host of new functions. The new features range from improved data exchange and an easier engineering workflow, more powerful communication, redundancy-related and fault-tolerant functions to new controllers and extended…
