EPA Test Methods 301 and 320 include statistical techniques for validating sampling methods in specific gas matrices. Several of these techniques were used to analyze extractive FTIR data collected at a municipal solid waste incinerator and to validate the method for hydrogen chloride (HCl) measurements. FTIR results for carbon monoxide (CO), sulfur dioxide (SO2), and nitric oxide (NO) were also compared to measurements recorded by the facility's continuous emissions monitors (CEMs). Presented are discussions of the equipment, spectral analyses, and statistical comparisons of the various test methods.
Pneumatic conveying by vacuum is quickly becoming one of the most popular means of transport for a variety of pharmaceutical products. The use of either dense or dilute phase vacuum transfer can be applied to tabletting operations such as the loading of blenders, sifters, mills, capsule fillers, tablet presses, and even tablet and capsule handling without damage to the finished product.
Granulation is a process in which powder particles are made to adhere to each other, resulting in larger, multiparticle entities, so called granules. If such a process is performed without adding liquids, this is called dry granulation.
One of the most critical measurements in the processing industries is rate of flow. In 2010, the ARC Advisory Group estimated the total instrumentation market (not including process analytical devices) to be $13.4B.
The ABBEMAT refractometers have gained a worldwide reputation for their high performance and accuracy. The new generation of instruments continues this tradition, utilizing the latest progress in opto-electronics and data processing technology.
This dust-proof, quick-acting separator point comes with a powerful, long-life, maintenance-free pneumatic drive. It is extremely flexible — versions for horizontal and vertical installation are available (standard nominal diameters: 40 – 150 mm).
