GASERA LAUNCHES A NEW GREENHOUSE GAS ANALYZER

Our new portable product, GASERA ONE GHG greenhouse gas analyzer offers a selective, reliable and simultaneous analysis of methane (CH4) and nitrous oxide (N2O) greenhouse gas emissions with highly accurate low-ppb detection limits.

Greenhouse gas (GHG) emissions especially methane (CH4) and nitrous oxide (N2O) play a significant role in the global warming and climate change. Methane (CH4) has 25 times and nitrous oxide (N2O) 296 times higher GHG effects than that of carbon dioxide (CO2), which leads to the secondary atmospheric contamination. The global warming and climate change are continuing to be a threat to our planet.

Even though there there has been a small dip in the greenhouse gas emission due to the Covid-19, but smaller than many climate researchers expected given the scale of the pandemic, and is not expected to last once the virus is brought under control. There is a growing need to measure, analyze and monitor the greenhouse gas emissions in many areas from research to food production and agriculture, and from waste management to biogas production, among others. We believe that our GASERA ONE GHG greenhouse gas analyzer offers and excellent tool to these monitoring needs. We see excellent marketing opportunities for the product globally as it matches the need for accurate monitoring of greenhouse gases.”, says Gasera’s CEO Dr. Ismo Kauppinen.

Now Gasera Ltd., a Finnish high-tech company, launches a disruptive analyzer, which is based on the proven technology of the GASERA ONE platform. It offers an affordable and easy-to-use tool for continuously monitoring the background levels of methane (CH4) and nitrous oxide (N2O). GASERA ONE greenhouse gas concentration analyzer can achieve below 10 ppb detection limit for CH4 and 2 ppb detection limit for N2O.

“There are several significant advantages in the product: It has an intuitive, user-friendly interface, which is easy to use with a single dial. Second, its patented photoacoustic detection scheme combined with a quantum cascade laser source, and third, it gives an exceptionally high level of stability with a re-calibration period of 12 months offering a low total cost of ownership,” says Kauppinen.

GASERA ONE in formaldehyde monitoring in hospital

Formaldehyde (chemical formula HCHO or CH2O) is used in hospital setting in all diagnostic procedures in anatomic pathology. The potential carcinogenicity of formaldehyde (HCHO) has prompted increasing preventive measures in anatomic pathology laboratories and new strategies aimed at innovating airborne formaldehyde monitoring systems. GASERA ONE in formaldehyde monitoring in hospital setting was conducted as a part of the study.

The last two decades have been crucial for the assessment of airborne formaldehyde (HCHO) exposure in healthcare environments due to changes in limits and reference values, definition of carcinogenicity, and new monitoring methods.

Dugheri et al. analyzed twenty years of experience in automatic, continuous airborne formaldehyde (HCHO) monitoring in the Pathology Laboratory and operating rooms. GASERA ONE FORMALDEHYDE was used as a real-time, continuous photoacoustic instrument to measure formaldehyde (HCHO).

The researchers found a significant decrease in formaldehyde (HCHO) exposure over a 20 year period. The formaldehyde exposure significantly dropped, which coincided with optimised histology workflow and implementation of safety practices. 

The researchers also found that “GASERA ONE FORMALDEHYDE, with a dynamic range 100,000 times above HCHO detection limit, is a valid alternative. Besides, it is highly selective against carbonyl compounds and other volatile organic compounds (VOCs), while its response time and detection limits are lower by one order of magnitude compared to Formaldemeter htV-M.”

This study demonstrates the applicability of the GASERA ONE FORMALDEHYDE as a continuous monitoring tool in occupational health and safety. Read more:

GASERA ONE PULSE IN HEALTHCARE WORK SAFETY STUDY

GASERA ONE PULSE in healthcare work safety study to measure tracer gas, Sulphur Hexafluoride  (SF6). Healthcare workers treating patients infected with emerging and re-emerging viruses are aware of the risks they face, particularly aerosol transmission.

The aim of this study was to investigate and characterise the risk of potential aerosol transmission of infectious agents from patients to their HCWs in typical encounter scenarios in hospital isolation rooms to improve the work safety in healthcare.

A study conducted at the Turku University Hospital and University Hospital of Leicester investigated how the risks can be reduced by optimising ventilation methods as part of an engineering control approach to infection control and the study was based on laboratory experiments carried out in a full-scale isolation room model at TUAS Indoor Environment Laboratory.

In the study, tracer gas Sulphur Hexafluoride (SF6) measurements were carried out for several experimental cases to assess the effect of different parameters on the spreading of the patient’s exhaled airborne contaminants and the HCW’s exposure to them. In addition to the SF6 gas tracer, an organic live-attenuated vaccine virus tracer was used in this study for enhanced realism.

The SF6 tracer gas concentration was measured from the room exhausts and the inhalation of the HCW manikin. The sampling and measurements were carried out with the GASERA ONE PULSE multigas analyzer. This study demonstrates the applicability of the GASERA ONE PULSE in healthcare work safety research.

GASERA ONE PULSE is a versatile and easy to use multi-gas monitoring solution. It offers accurate ppb detection for a range of uses such as detecting Suphur Hexafluoride (SF6), anesthetic gas monitoring, occupational health and safety, among others.

FORMALDEHYDE (HCHO) PHOTOCATALYSIS RESEARCH WITH GASERA ONE

Formaldehyde (HCHO or CH2O), as one type of volatile organic compounds (VOCs), and its derivatives have long-term effects on human body and even causes cancer.

Formaldehyde is a widely contained in furniture materials, paint, and adhesives that has become one of the most concerned indoor pollutants due to sustaining release.

In a recent study, Wenjun Wang et al. proposed a sustainable and green approach to synthesize an efficient N, Ca co-doped TiO2 photocatalyst (TIMP) by using the insoluble matrix proteins (IMPs) extracted from abalone shell. Link to original paper in comments.

In this study, the concentration of HCHO, CO, and CO2 were monitored online by GASERA ONE photoacoustic infrared multigas monitor. This is further evidence of the applicability of the GASERA ONE platform products in demanding formaldehyde (HCHO) gas analysis, monitoring and scientific research.

GASERA ONE is a photoacoustic multi-gas analyzer platform that serves a wide variety of research and industrial applications. GASERA ONE platform can be tailored to suit multiple applications by selecting optimal lasers and/or light sources.
