Applications about using INNOVA Products
LumaSense has a wide range of products for measurement of gases within numerous applications. Our high quality equipment uses the latest technology within Infra-Red Photoacoustic Spectroscopy (PAS) and Magnetoacoustic Spectroscopy (MA). Our specialised equipment for Indoor Climate applications can evaluate Ventilation Systems, Thermal Comfort and Heat Stress.
R134a in Mobile A/S systems
In order to evaluate refrigerant emission from mobile A/C systems or its components such as hoses, seals, O-rings or joints, the change in concentration of refrigerant versus time is measured in a closed testchamber of known volume. Such measurements have been done by Delphi Thermal & Interior Technical Center, Lockport, NY using the Photoacoustic Multi-gas Monitor - INNOVA 1314 in their laboratory for measurements of R134a, R152 and Carbon Dioxide.
Hospital Gas Monitoring in Operating Theaters
Occupational exposure to inhalation of anaesthetic gases should be minimised as it may lead to adverse health effects for the personnel exposed. Many countries pay special attention to workers safety in operating theatres which is leading to increased awareness of recommended exposure levels and measuring methods.
Comparison of Temperature Measurement Methods for Evaluation of Thermal Comfort in Vehicles
A new standard, ISO/DIS 14505 is under preparation, dealing with the assessment of the thermal environment in vehicles, based on the equivalent temperature. The scope of this paper is to demonstrate the different results obtained when evaluating the thermal environment inside a vehicle, using the three well known parameters, air temperature, operative temperature and equivalent temperature.
Contaminated Soil - Chlorinated Compounds in Soil-Gas
Online Measurement of Chlorinated solvents in contaminated soil. Contaminated soil is a serious and wide spread problem that normally has to be solved to avoid pollution of the ground water reservoir. The Photoacoustic Multi-gas Monitor - INNOVA 1312 was chosen for this application because of its long term stability and low detection limit.
Multi-point Fermentation Monitoring
One of the features for the Fermentation Monitor - INNOVA 1313 is the very low sample rate (130 ml/min). This makes it possible to measure the Fermentation process also in very small fermentors and thus applicable for Labs, Pilot Plants and Production Scale Fermentors. Using the Multi Point Sampler - INNOVA 1309 many fermentors can be monitored.
Measurement of Greenhouse Gases
Many gases in the atmosphere absorb infra-red radiation and participate in the "natural greenhouse effect", trapping the heat from the sun and lifting the average temperature of the earth. Measurement of atmospheric concentration of Water Vapour, Carbon Dioxide, Methane and Nitrous Oxide can be done with the Photoacoustic Field Gas-Monitor - INNOVA 1412.
Methyl Metacrylat and Anaesthetic Gases
In Operating Theatres high concentrations of anaesthetic agents and vapours from other substances can be found. Measurement with a Photoacoustic Multi-gas Monitor - INNOVA 1312 of Nitrous Oxide, Halothane, Enflurane, Isoflurane, 2-propanol, Carbon Dioxide and MethylMetAcrylat has been used during a hip replacement operation at a hospital in Oslo, Norway.
Monitoring SF6 in the Power Utility Industry
The amount of Sulphur Hexafluoride (SF6) used in the Power Utility Industry has been increasing. The gas is used mainly as an insulator for electrical switch-gear and control-gear. The Photoacoustic Multi-gas Monitor - INNOVA 1312 is excellent for monitoring leaking Sulphur Hexafluoride from high-voltage equipment due to a low detection limit and high linearity.
VOCs in Central Ventilation System
Pharmacia in Uppsala, Sweden, use Chloroform as an extractant in the production of Healon. To reduce the risks to the work-force, a centralised ventilation system draws the air from the various areas. Pharmacia wanted a real-time monitoring system that could monitor the amount of Chloroform in the vent emissions and used the Photoacoustic Multi-gas Monitor - INNOVA 1312.
Monitoring Formaldehyde in a Chipboard Manufacturing Plant
Formaldehyde is a toxic, carcinogenic gas, which affects the mucous membranes such as the lungs, eyes and nose. Traditional methods to measure Formaldehyde are normally time consuming. However, the Photoacoustic Multi-gas Monitor - INNOVA 1312 is capable of measuring up to five gases simultaneously with-in 75 seconds.
Organic Solvents at a Printers
High quality printing often requires the use of printing inks that have organic solvents as a carrier. To monitor the emission from a ducted extraction system a Fast Response Triple- gas Monitor - INNOVA 1311 was recommended. This monitor uses the PAS/MA technique and a special optical filter, which can measure the desired volatile organic compounds.
Measurement of Airflow in Automobile Ventilation System
The following article presents the principles of the tracer-gas measurement method along with the techniques used to determine the different flows of a vehicle ventilation system. Examples are presented both of measurement of flow from the individual inlet vents and of the total flow under varying operating conditions.
Ventilation Performance in Subway Station
The air quality in a subway station with many diesel trains sets high demands on the ability of the ventilation system to remove obnoxious gases and particles. In order to evaluate the ventilation system and air quality two tracer-gas monitoring systems were used.
Automotive Industry in Korea - Measurement of Thermal Comfort
Evaluation of the Thermal Environment in cars is normally a very complex task. However, with the use of the Thermal Comfort Datalogger - INNOVA 1221 and the manikin INNOVA "Flatman" a detailed evaluation can be performed. The manikin is equipped with up to 8 Dry Heat Loss Transducers - INNOVA MM0057 for measurement of the Equivalent Temperature and calculation of the PMV index.
