Traditional ECD (electrochemical detector) H₂S sensors tend to have a short lifespan under such conditions, resulting in frequent and costly replacements.To reduce maintenance demands and enhance monitoring reliability, a gas analyzer equipped with a long-lifespan H₂S sensor was required for effective biogas system operation.SolutionsAfter evaluating various technologies and suppliers, CG ...
Silica Monitoring is a Big Problem Typically, exposure monitoring for RCS has involved occupational hygienists setting up fixed location or wearable instrumentation, including a pump connected to a sampling head that collects samples on a filter. These samples are then sent off to a lab for analysis. This exposure reporting is ...
Introduction Biogas, a renewable energy source produced from organic waste, plays a critical role in reducing greenhouse gas emissions and providing sustainable energy. One of its primary components, methane, is essential for energy production, making its accurate measurement vital. This guide explores how to measure methane in biogas, best practices, and the advantages of Cambridge ...
These improvements led to almost zero mortalities in 2019, however, staff still relied on grab samples to determine whether to shut off the pumps, and the sampling process took time to complete. ...
Usually, ChemScan products are connected to multiple submersible pumps that bring samples up from the different zones of the treatment basins and through the analyzer system. But this design was less effective for McDowell’s infrastructure, which features large vertical mixers and a single main sample pump connected to ...
These devices include a built-in sampling system and are easy to transport. The user interface allows users to establish sample parameters, collect data, and, if necessary, transmit this data to an external system. The air sampling system, whether a vacuum pump or blower, must also provide an adequately filtered exhaust system to ...

In our case, our products and patents involve the use of ultrasonic pumps to move air. An ultrasonic pump is a special kind of pump that relies on flexible piezoelectric discs driven at high frequency (about 25,000 cycles per second). ...
Understanding the Impact of Filters on Portable FIDs Filters are a key component in the efficient operation of portable FIDs (Flame Ionization Detectors). Their lifespan depends on usage hours and the environment, with water exposure being a critical factor. Technician diligence in maintaining these filters is crucial for the longevity of portable FIDs. Our portable FID filters feature a ...
For instance, deionized water within the system needs to possess high purity to ensure that the flowing water does not contaminate samples or reagents. Additionally, the pump itself must avoid releasing even trace amounts of pollutants. ...
You may wish to measure O2 and / or CO2 without using the pump to draw sample. For example, measuring the oxygen from a rigid bottle with 50cc (or 50mL) of headspace can create a vacuum condition if you draw 15cc of headspace. This challenge is easily overcome using a syringe that we can provide. Sample can be manually injected into our ...
This is because our analyzers use an internal pump to draw in sample, and the flow is only allowed to travel in one direction – out. You could correct for this discrepancy, but sampling this way is not recommended. The long term durability of the analyzer, specifically the sensor and pump, can be impacted by pulling on a ...
ANSI N13.1-2011 Stack Sampling Location Qualification Testing The primary consideration in stack sampling is to have a well-mixed, representative sample entering the sample probe. ...
The European Commission have announced a proposal to introduce their first-ever workplace exposure limit for Dissocyanates. Diisocyanates describe various chemicals that are often grouped based on their common properties, and which can cause respiratory diseases like asthma. The Commission’s impact assessment estimates that currently, 4.2 million workers in the EU are exposed to ...
Let me share one of our challenges. It is sometimes difficult to explain what we’re selling. That’s not because we don’t know what we’re selling, we have a small catalog. We have difficulty explaining what we’re selling because we fall into the trap of trying to explain what we’re selling by analogizing to the products that came before them. But we know this ...
Researchers can use these chromatograms to further break down the chemical properties of the sample mixture. The ratio of the peak size is related to the amount of substance in the sample. Area under a mountain peak is used to determine the sample size. For example, to determine a component in a sample, a standard ...

The pump-probe technique can be described by a sample being photo-excited by a light source (pump pulse), whereby a second light source (probe pulse) is measured for changes in absorption as a function of wavelength and time. ...
The Guardian NG Gas Monitor is wall-mounted, in an IP54 enclosure, with an integral power supply and sample pump, allowing samples to be taken remotely from over 30 meters away. ...
Its precise weigh cell and powerful peristaltic pumps approach optimizes dilutions. Samples are inserted inside sterile bags, which are then held by a sterility-ensuring holder. ...
