Using an air sampler for microbial air contamination monitoring: step by step
Microbial air contamination monitoring is a key process in facilities with special air cleanliness needs. Air sampling is a regulated process that, with following simple steps, we can obtain an indicator of the quality of the air. Do you want to know how to perform an air sampling? IUL’s air samplers are very compact and designed for easy transportation. In fact, IUL Spin Air samplers give ...

Active Air Sampler Comparison Study in Remote Settings
Abstract Environmental monitoring relies heavily on viable active air samplers to provide data about microbial presence in a clean area. In a firm's study to determine a better method of microbial collection, the BioCapt Stainless Steel was compared to their existing sampler and shown to have much higher microbial and mold collection counts. This result is attributed to high collection ...

The importance of avoiding cross-contamination. Reasons to use a microbial air sampler in your workspace
Nowadays, companies are more and more concerned about the air quality in indoor spaces. Pharmaceutical and Personal care industries are not the only ones affected, it’s also an important issue for food & beverage, hospital, and environmental application. That is why it gets so important to use a microbial air sampler in any workspace. If the air quality is not adequate, it can impact ...

Table of Statistical Corrections According to Feller for the BioCapt® Microbial Impactor in Microbial Air Sampling
Abstract This application note uses the principle that, as the number of viable particles — colony forming units (CFUs) — impact on an agar plate increases, the probability that viable particles will enter unoccupied space decreases. The values within Tables 1 and 2 are shown at flow rates of 25–50 LPM and 100 LPM. BioCapt microbial impactors are used on all Particle Measuring ...

Selecting an Air Sampler for Bioaerosol Collection
Indoor Air Quality (IAQ) investigators should select cost effective, efficient and the highest quality samplingequipment for evaluation of indoor environments. Particle impaction onto an adhesive surface (non-viable) or into culture media (viable) are the most widely used techniques to evaluate the presence and levels of airborne bioaerosols, particularly in non-industrial indoor environments. ...

Spatial mapping of the city of Lisbon using biomonitors
Biomonitoring is used to study the performance of a single air sampler as representing air elemental concentrations in Lisbon. A database of chemical elements' concentrations was obtained by analysing exposed lichens and bark, hung on courtyard trees of 22 Lisbon basic schools from January to May 2008 and June to October 2008 (winter and summer campaigns). Electric conductivity was also measured ...

The Spectrex air sampler ideal for industrial hygiene.
Comments by an industrial hygiene supervisor in Texas "The Spectrex PAS-500 is a great tool for collecting both personal and area air samples. I have yet to have a worker complain about having to wear the pump. The workers appreciate the drastic reduction of weight and size when compared to the traditional low volume pumps. The best advantage of the PAS-500 is the clip that holds the pump ...

Effectiveness, Suitability, and Performance Testing of the SKC® Deployable Particulate Sampler (DPS) As Compared to the Currently Deployed AirmetricsT
Epidemiological studies have linked particulate matter (PM) exposure to morbidity and mortality from cardiovascular and respiratory disease. In order to monitor and assess the potential PM health risk to deployed military personnel, the U.S. Army must field a portable sampler that can accurately sample particles with an aerodynamic diameter less than or equal to a nominal 2.5 mm (PM2.5). In the ...

Control Microbes with Monitoring of your Cleanroom
Microbial Environmental Monitoring To achieve compliance to regulatory guidance, a microbial monitoring program includes the following components: Active air (room or enclosure environment) Passive air (settle plates) Surfaces (contact plates and swabs) Personnel (gloves and garments) Compressed gases Materials and equipment that could compromise product microbiological quality Cleaning ...

Apply appropriate models in the study of dry deposition fluxes of particulate matter and polycyclic aromatic hydrocarbons (PAHs) in Tsukuba, Japan
In this study, plates for downward flux and upward flux were used to measure atmospheric dry deposition fluxes for particulate mass and polycyclic aromatic hydrocarbons (PAHs) in TERC (Tsukuba), Japan. Ambient particles concentrations were also collected using a high-volume air sampler, and ambient particle size distributions between 0.01 μm and 13.1 μm were measured using a low-pressure cascade ...

The radiological impact on some workers due to the natural radionuclides from some industries
A total of 37 different soil samples and 22 air samples were collected from natural industrial sources. The air samples were collected at a height of 1 m above the ground on 10.4 cm diameter filter paper (with a desired collection efficiency) using a high-volume air sampler. The activity concentration levels of naturally occurring radionuclides such as the U-238 series and Th-232 series were ...

Polybrominated diphenyl ethers, dechlorane plus, and polychlorinated biphenyls in tree bark near the upper Yellow River, China
Willow tree bark samples from urban and rural sites in Inner Mongolia, Ningxia Province, and Gansu Province, in the Yellow River basin, were analyzed for polybrominated diphenyl ethers (PBDEs), dechlorane plus (DP), and dioxin‐like polychlorinated biphenyls (DL‐PCBs) to compare their relative levels in air in these areas (i.e., treating bark as a passive air sampler). No difference was found ...

PM10, CO and NOx concentrations in the Tuhobic road tunnel, Croatia
Particulate matter (PM10 particle fraction) and trace gases (CO, NO and NO2) have been sampled during six weeks in the Tuhobic road tunnel, Croatia, whose length is 2140 m. Eight mini portable air samplers (Air Metrics, USA) were placed in the centre of the tunnel at a height of 1.70-m above the ground. PM10 samples were collected on Whatman quartz filters with the diameter of 47 mm, while gases ...

Where’s the Noise? Where`s the Pulsation? A quick explainer on UPAS technology
We’re a team of mostly scientists and engineers and that means we’re going to come up with nerdy sometimes-too-literal naming conventions. Where does the UPAS acronym come from? UPAS stands for Ultrasonic Personal Aerosol Sampler or as we’re seeing more and more folks expand beyond aerosols; UPAS can also stand for Ultrasonic Personal Air Sampler. So why that name? In this post ...

How to Achieve Good Indoor Air Quality in Operating Rooms
There are two primary objectives in achieving acceptable air quality in the operating room: (1) control of anesthetic gases for the benefit of operating room staff, and (2) infection control for the benefit of the patient. Control of Anesthetic Gases Supply and scavenging systems, as well as general ventilation in the OR, must be functioning optimally for the surgical staff to be protected from ...

Assessing atmospheric concentration of polychlorinated biphenyls (PCBs) by evergreen Rhododendron maximum next to a contaminated stream
Conifers are often used as an “air passive sampler”, but few studies have focused on the implication of broadleaf evergreens to monitor atmospheric semivolatile organic compounds such as polychlorinated biphenyls (PCBs). In this study, we used Rhododendron maximum (rhododendron) growing next to a contaminated stream to assess atmospheric PCB concentrations. The study area was located in a ...

Particulate matter and particle-bound polycyclic aromatic hydrocarbons in the Dapu road tunnel in Shanghai
Airborne Particulate Matter (PM) was collected in a cross-river road tunnel using portable air samplers and a cascade impactor. Sixteen EPA priority Polycyclic Aromatic Hydrocarbons (PAH) in the PM were quantified by gas chromatography/mass spectrometry. Profiles and diagnostic ratios of PAHs were investigated, and size distribution of PM mass and PAHs were discussed. High concentrations of PM2.5 ...
