  • CO2 Tank Safety Precautions
    Whether you use a CO2 cylinder or a bulk CO2 tank system, you should be aware of CO2 tank safety. Thousands of liquid carbon dioxide cylinders and tanks are used across the country for soda or beer carbonation, for refrigeration, industrial purposes, medical and scientific facilities, and even
  • CO2 Tank Safety & CO2 Cylinder Safety
    Whether you use individual CO2 cylinders or a bulk CO2 tank system, you should be aware of CO2 tank safety. Thousands of liquid carbon dioxide cylinders and tanks are used across the country for soda or beer carbonation, for refrigeration, industrial purposes, medical and scientific facilities
  • Liquid Cooling a Laser for System Optimization
    The performance of high-powered lasers depends on effective cooling. High-powered lasers generate a significant amount of heat that must be removed from the laser system to avoid overheating critical components. Carbon dioxide (CO2) lasers, excimer lasers, ion lasers, solid-state lasers, and dye
  • Bottoms Up: How Better Mixer Chilling Can Improve Your Food Process
    When it comes to cryogenic chilling, processors may be better starting at the bottom. The bottom of their mixer, that is. Strategically injecting. cryogens such as carbon dioxide or liquid nitrogen directly into the bottom of a mixture chills food faster, more effectively and at a lower cost than
  • Why Measure CO2?
    in Confined Spaces. Portable handheld CO2 Meter. Carbon dioxide, in the form of underground off-gassing, dry ice or liquid CO2 delivery systems, or portable heaters can pose a potential deadly threat. Because it is odorless and colorless, workers can easily be overcome by high levels of CO2 in enclosed
  • Dry Ice vs. Soda Blasting
    Abrasive blasting with sodium bicarbonate (i.e., baking soda) is a popular surface-cleaning technique, but there are equally popular alternatives as well. One alternative method is dry ice blasting. Dry ice blasting involves propelling dry ice, which is solid carbon dioxide, against a surface
  • Mission Supercritical
    in key benign solvents --supercritical carbon dioxide and near-critical water, to name two --opening the door for pharmaceutical applications. Supercritical CO2 is carbon dioxide that has been compressed to a degree where it exhibits some liquid, solvent-like properties. It is readily available
  • The Pitfalls of Process TOC Analysis and How To Avoid Them (.pdf)
    acid is added to the sample, dropping its pH to approximately 2.0. At this point, the IC is converted to carbon dioxide (CO2) gas, which is stripped out of the liquid by a sparge carrier gas. The remaining inorganic carbon-free sample is then delivered to the Oxidation Chamber.
  • Low-Risk Lyophilization
    ? In this instance, what is the tolerable concentration range of the formulated solution that can be expected to prevent one formulated lot from precipitating while another does not? Is the ionic strength of the formulated liquid so low that the solubility of carbon dioxide in the liquid impacts the pH
  • Tuning in to New Solvents
    Operational Excellence & Lean Six Sigma organic solvents mixed with carbon dioxide gas, which expands their volume by a factor of 10 or more. Nutraceuticals production has moved in the direction of GXLs, by using ethanol cosolvent as a polar modifier with scCO . This results in a solvent medium
  • Tuning in to New Solvents
    hydrolysis using CO expanded liquid and hot water Nolen, S.; Lu, J.; Brown, J.; Pollet, P.; Eason, B.; Griffith, K.; Glaser, R.; Bush, D.; Lamb, D.; Eckert, C.; Liotta, C.; Thiele, G.; Bartels, K., Olefin Epoxidations Using Supercritical Carbon Dioxide and Hydrogen Peroxide Without Added Metallic
  • PROTECT YOUR INVESTMENT: Five factors to consider before making the switch to aftermarket oil
    . such as: * Miscibility: The performance of a hydrofluorocarbon. (HFC) or carbon dioxide (CO2) system is optimized when. the lubricant and refrigerant mix to form a single, clear. phase (that is, they are miscible). Miscibility lowers the. viscosity of the lubricant carried through the system,. so the lubricant can
