Viasensor is a leading provider of environmental analyzers, equipment and products used in clinical environments, hospitals, laboratories, incubators, Federal Border-Custom agencies, food production and indoor air quality (IAQ).
Traditionally laboratory incubators need to run at a constant temp, humidity and CO2 level (approx 5%) to maintain the correct conditions for, the best growth of cell cultures, embryos for in vitro fertilization
The incubators themselves will have a built in monitoring system for CO2, but because it is critical that these levels are kept constant, a portable analyzer, such as the G100, can quickly and accurately confirm the CO2, O2, humidity and temperature levels. This functionality is required by lab technicians, but is also an important part of the toolkit for service engineers for when incubators are being serviced. Learn about the G100 & G110.
The background level of CO2 in air is approx 300-400ppm and any significant increases over time (each country will have own exposure limits) can cause issues with staff who are constantly working in this environment (tiredness, headaches, lethargy etc). While CO2 is the key factor in sick building syndrome, O2, humidity and temperature levels are also significant. Learn about the G150.
N20 is used as a sedative in hospitals - particularly operating rooms, x-ray departments, dental practices and veterinary clinics, where medical staff is at risk of long term exposure. The maximum exposure level considered acceptable over an 8 hour period (known as a time weighted average, TWA) is set as a maximum limit country by country.
Monitoring may be by placing an analyzer within a room, set up with a trigger alarm and data log. Alternatively, a unit can be attached to the user (on a belt clip) with the tube attached just over the users shoulder to record levels of N20 in the breathing zone (more critical for dentists and in operating rooms, where the user may be spending a lot of time around the main source of the gas). Again immediate alarms or TWA can be recorded to record exposure. Leak detection in N2O storage areas is also important.
Verification of piped medical gasses (N20 and O2) in medical facilities (hospitals, nursing homes) is also a critical area of gas monitoring. The gasses will be used either to aid a patients breathing or to sedate them. It is of course critical that these gasses are of a high quality and not contaminated.
It is a legislative requirement that a health and safety officer or medical consultant regularly go around the hospital taking samples from gas outlets and checking that the gasses N20 and O2 are kept to a high standard (99% +/- around 1% or better) and that CO2 and CO levels are below national standards (500ppm CO2 and 5ppm CO). Learn about the G200 & G210.
The G150 Stowseek is used specifically for accurately monitoring ppm level CO2 immigrant detection. Used with a 1m probe for insertion into vehicles and containers, it can quickly identify elevated levels of CO2 to help detect possible stowaways.
