The main instruments and methods of measuring concentration (gravimetric, optical, and microbalance) and size distribution Scanning Mobility Particle Sizer (SMPS), Electrical Low Pressure Impactor (ELPI), and others were described and compared. The aim of this work was to help researchers choose the most suitable equipment to measure particulate matter. When choosing a measuring instrument, a researcher must clearly define the purpose of the study and determine whether it meets the main specifications of the equipment. ELPI and SMPS are the suitable devices for measuring fine particles; the ELPI works in real time.

The present work reports such data for methanol, 1-propanol, 2-propanol and 1-butanol along seven isotherms in the temperature range from 220 K to 500 K and a pressure of up to 125 MPa. The overall expanded uncer- tainty varies between 0.07% and 0.11% with a confidence level of 95%. The employed experiment is based on a double path length pulse-echo method with a single piezoelectric quartz crystal of 8 MHz, which is placed between two reflectors at different path- lengths.

  • Anesthesia Gas Monitoring: Evolution of a De Facto Standard of Care
    Anesthesia Gas Monitoring: Introduction The overriding concern for patient safety during surgery Evolution of a de facto has given rise to the development and adoption of a num- ber of technologies, whose use is taken for granted every Standard of Care time a patient undergoes general anesthesia. These tech- nologies include airway pressure monitoring and breath- ing system disconnect alarms, monitoring of inspired oxy- gen, monitoring of expired CO2, and pulse oximetry. The ongoing technical advancements in the field of respiratory gas monitoring of the five potent inhaled anesthetic agents, N2O, CO2 and O2; the valuable information they provide to the anesthesia caregiver, the shrinking of the physical attributes (i.e. size and weight) of these sensors and mon- itors, and their lower purchase cost, has seen their use in most modern operating rooms in the world. The feedback they provide to the clinician has become an indispensible tool designed to ensure the patient’s safety during the peri- operative period. Monitoring the anesthetic gases deliv- ered by the anesthesia delivery system can alert the care- giver to a number of potentially adverse conditions such as inadvertent agent overdose, timing to reach MAC awake (pseudo awareness detection), error of a vaporizer filled with incorrect agent, monitoring of uptake and distribution, and assurance that the desired agent concentration is being delivered, especially when low flow anesthesia is administered. 1 In his ASA refresher course, Hazards of the Anesthesia Workstation, Dr. James Eisenkraft, Professor of Anesthe- siology at the Mount Sinai School of Medicine, in New York City, points out that hardware failures in modern anesthe- sia delivery equipment are rare.
