The Coriolis Compact is a lightweight, battery-operated air sampler designed to capture bioaerosols directly in the environment, delivering samples fully compatible with PCR, culture, and sequencing workflows, with no liquid media required on-site.Independent validations span four distinct environments: SARS-CoV-2 detection in indoor settings, H5N8 avian influenza monitoring on ...
Materials often owe their performance to subtle differences between surface sites, yet these variations are not always easy to distinguish experimentally. As temperature changes, molecules bound to a surface respond in ways that reflect how and where they are attached. Temperature programmed desorption uses controlled heating to trigger such responses in a systematic way. When evolved gas ...
Catalyst deactivation studies are central to maintaining efficiency in industrial chemical processes, including petroleum refining, petrochemical production, syngas and hydrogen manufacture, environmental catalysis for emissions control, and large-scale chemical synthesis such as ammonia and methanol production. Over time, catalysts lose activity due to carbon deposition, sulfur poisoning, and ...
It lets scientists determine what an object is made of—element by element—without taking samples or damaging the surface. In the last few decades, that combination of precision and gentleness has changed how we understand some very famous objects. ...
The chemistry of a material’s outermost nanometres often determines its functional performance, making accurate surface characterisation vital for modern materials research. Yet, analysing these nanometre-scale layers is inherently challenging, as many surface-sensitive chemistry techniques, like AES, can modify the material or disturb its native chemical composition and techniques like EDX ...
The following is a systematic analysis from the core dimensions: I. Sample Characteristics matrix complexity Organic matter content: Biological samples (plants, blood) require digestion with strong oxidizing acids (such as the HNO3-H2O2 system). ...
Seasonal changes can affect runoff, groundwater, and surface water supplies, making environmental sampling and water filtration more important than ever. ...
It is well known that the advantages of nanomaterials include expanded active surface area and the creation of new features that do not exist in the bulk state. ...
Condensing water can add to trapping the particles on the surface. However, when the morning traffic picks up, the turbulence starts, and the street surface dries. ...

Nitrogen is the adsorbent most commonly used by the specific surface area (BET) method, and the specific surface area ranges from 0.1 to 1000m2/g. ...
Introduction Microbiological sampling within a pharmaceutical manufacturing facility is performed using several methods: surface sampling passive aerosol (air) environmental sampling active aerosol (air) environmental sampling Each of these methods produces a result based on the growth of microbial ...
In the pharmaceutical manufacturing industry, ensuring sterility and minimizing microbial contamination are critical for maintaining product quality and safety. Microbial sampling is a key component of environmental monitoring, and understanding the optimal criteria for sampling can significantly impact the effectiveness of sterility assurance ...
The spectrophotometer measures the difference in light intensity passing through the sample and a reference sample (usually pure solvent) to determine the sample's absorbance of a specific wavelength of light. ...
Principle Electron microscopy imaging of protein samples at extremely low temperatures, by collecting a large number of images and combining them to construct a three-dimensional structure. 2. ...
Critical Dimension Measurement is crucial in industries where precision matters most. Imagine making the tiniest parts for your smartphone or the chips that power your computer. Getting those sizes right is critical. Let’s explore why measuring these dimensions accurately is so important and how it’s ...
In addition, it can help us to examine the surface of samples. This technique allows us to see if any changes have occurred to a surface because of its contact with ions. ...
Here’s what ESdat offers:Define Sampling Locations: Easily designate sampling locations for groundwater, surface water, soil, or landfill gas monitoring.Specify Laboratory Samples and Analyses: Specify the required analyses and containers for laboratory samples, ensuring accuracy and consistency.Recurring ...
The scanning electron microscope (SEM) allows us to observe the world in a level of detail that was previously unattainable. SEMs scan a sample's surface with a concentrated electron beam to create high-resolution images. ...
Three miniDOT® Loggers were deployed, one at the surface and one at the bottom of the deepest, still depths of the reservoir and the third at the bottom near a highly active inflow/outflow pipe. ...
Rotary Evaporator Rotary evaporators are used for removing solvents from a sample via a method of evaporation. They are ideal for solvents with low boiling points. They offer an accurate, more efficient separation technique as they increase a sample’s surface area, which enables a solvent to be separated quickly. ...
