Real-Time Gas Analysis and Reaction Monitoring using Mass Spectrometry


Gas chromatographs are commonplace in labs worldwide as workhorse instruments for the identification and purification of unknown chemical compounds. However, despite the abilities of gas chromatography (GC), GC alone cannot always be used for the specific identification of chemical compounds. As a result, such instruments are often coupled to mass spectrometers, where the ability to mass-resolve the peaks in a gas chromatogram allows for greater confidence in sample identification. Gas chromatography mass spectrometry (GC-MS) is often considered the ‘gold standard’ for forensic substance identification and it is now widely used in areas such as pharmacology, chemical synthesis and in the petrochemical industry. Continuous and Accurate Reaction Monitoring It is now possible to design GC-MS instruments with sufficiently short run times to be used for ‘real-time’ analysis. This type of on-line analysis provides constant qualitative and quantitative information on the evolution of chemical concentrations or the formation of new species in...

The Guide to Instrument Valves

Instrument Valve Introduction: Instrument valve is an attachment on the pipeline, usually a micro-control device, as the media off or change the media flow. Main types of instrument valves are: needle valve, needle valve, needle gate valve, micro-solenoid valve. In order to meet the factory live, many manufacturers are developing instrument valve new features in recent years. These mainly focus on multi-pass, pressure regulation, flow regulation, zero leakage, and confluence diversion direction to make substantial improvements.   Instrument Valve Application: The main function of the instrument valve is throttling, on-off, flow regulation, pressure regulation, confluence, diversion, sampling, and changing the direction of medium flow. Instrument valves are mostly made of stainless steel and its connection include: fast installment, internal and external thread, ferrule, welding. The diameter is from DN1 to DN20 mm, temperature ranges from -20.2 ℉ to 1076 ℉ . Pressure endures from PN0.1 to 100mpa and the main...

H2O backs clean water project in Nepal

This year, we are once again supporting the non-profit organisation Viva con Agua with a Christmas donation. The organisation builds and maintains water supply systems, enabling a constant supply of water, particularly to schools, public spaces and health centres. This time, we’re sending the donation to the Chitwan region in Nepal. This predominantly rural region is located southwest of Kathmandu, the capital of Nepal. Although the majority of the population in Nepal has secure access to drinking water, the conditions surrounding access to basic sanitation still pose a challenge. Viva con Agua is actively promoting the need to maintain and continuously improve the existing water supply system. True to its motto ‘ALL FOR WATER – WATER FOR ALL’, the Viva con Agua team is tirelessly working towards its goal of ensuring that everyone has access to clean drinking water. Now more than ever, such aid is especially important for Nepal,...

The Main Role of the Pressure Reducing Valve

With the wider use of machinery fittings, the valve industry has been boomingly developed. The market demand for pressure reducing valve is greatly enhanced as well. As a result, the purchase of pressure reducing valve has aroused attention. So, how can we choose the better pressure reducing valve? The principle of the pressure reducing valve is to reduce the water pressure by the local resistance of the flow channel in the valve to the water flow. The range of the pressure drop is automatically adjusted by the pressure difference between the inlet and outlet of the diaphragm or the piston connected with the valve flap. In recent years there have been some new types of pressure reducing valves, such as constant proportional pressure reducing valve. The principle of decompression is the use of valve body floating piston hydraulic ratio control, making entrance and exit side decompression ratio and the piston...

image
December 13, 2017 -- Survalent , a leading provider of advanced distribution management systems (ADMS), recenty announced that Mid-Ohio Energy Cooperative has reduced outage time by almost two-thirds since adopting SurvalentONE SCADA and OMS applications. Mid-Ohio Energy is a not-for-profit, customer-owned electric utility serving residential and commercial customers throughout central Ohio. 'In recent years, Mid-Ohio has been consistently recognized as one of the five utilities in the state with the lowest annual outage times,' said Mark Terrill, Director of Operations at Mid-Ohio. 'Our System Average Interruption Duration Index (SAIDI) dropped from 128 minutes in 2009 to just 46 minutes in 2016, a 64% decrease.' Mid-Ohio Energy has also earned an 87 rating on the American Customer Satisfaction Index (ACSI), the utility's highest-ever score on this important metric. Terrill attributes Mid-Ohio's success to a sharp increase in operational efficiency driven by SurvalentONE SCADA and OMS. The utility uses Survalent's SCADA system...

How Do Chemyx Syringe Pumps Work?


Warning: preg_match(): Compilation failed: regular expression is too large at offset 103215 in /home/civile9/ceengr.com/libraries/vendor/joomla/string/src/phputf8/str_ireplace.php on line 37

A syringe pump is a small, positive-displacement pump used to gradually transfer precise volumes of fluid. All Chemyx Fusion series syringe pumps are driven via a stepper motor. This stepper motor precisely turns a lead screw that is threaded through a pusher block, which causes the pusher block to move. When the pump is in infusion mode, the pusher block pushes against the plunger of a secured syringe, causing the fluid to be ejected at an accurate and precise rate. If the pump is capable of withdrawal, the plunger of the syringe is held by brackets on the pusher block. When the stepper motor turns in the opposite direction, the pusher block moves such that the syringe plunger is pulled, thus drawing fluid into the syringe. For the Fusion Series syringe pumps, the pusher block moves to the right for infusion and to the left for withdrawal. Controlled Elements All...

Tracking the environmental performance of industry in Europe: new interactive country profiles

Industry across Europe is responsible for more than half of all carbon dioxide, particulate matter and other key pollutants emitted into the air, according to updated industrial pollution country profiles published today by the European Environment Agency (EEA). The 33 profiles of the member countries of the EEA (EEA-33) give an updated snapshot of sources of industrial pollution across Europe. The interactive profiles summarise the latest data available (from 2015) related to industry, and cover air and water emissions, waste generation (in this case from 2014), energy and water use. The country profiles complement the EEA briefing 'Releases of pollutants to the environment from Europe's industrial sector,' published in July. Industry remains a major emitter of pollution Industry makes a significant contribution to Europe's economic wellbeing and is responsible for more than a fifth of economic value generated across the EEA-33. European Union policies — specifically the EU's Industrial Policy...

Bureau Announces 100% Allocation for South-of-Delta Contractors


With statewide snowpack at record levels, the U.S. Bureau of Reclamation today announced that South-of-Delta water contractors will receive 100% of their Central Valley Project contract supply for the first time since 2006. “Following the California Department of Water Resources exceptional March 30 snow survey results, Reclamation is pleased to announce this increase to a 100 percent allocation for our South-of-Delta water contractors,” said Pablo Arroyave, acting regional director for Reclamation. “However, as Governor Brown reminded us last week when lifting California’s drought state of emergency, the next drought could be around the corner. It is crucial that we remain vigilant in conserving our precious water resources.” Reclamation previously announced a 100% allocation for all CVP contractors with the exception of agricultural water service contractors South-of Delta. Those contractors – in the Delta Division, San Felipe Division, and the San Luis Unit – were initially allocated 65% of their contract...
