10 Automated Permeation Breakthrough Analysis Systems
When working with hazardous chemicals, appropriate protective clothing should be worn. These items of protective clothing should be tested to ensure they offer a suitable level of chemical protection. Testing the rate at which a chemical permeates through a material determines the level of protection it can offer. To achieve certification as ‘chemically protective’ by EN ISO 374-1, a glove must accomplish certain breakthrough times against several challenge chemicals.
Ellutia offers a complete system for the automatic analysis of permeation breakthroughs. The system comprises of a number of permeation cells. Optional automated challenge chemical introduction can further increase sample throughput and automation. Once each cell has had the challenge chemical applied on one side of the sample material and automatically samples the headspace from the other side periodically to plot the permeation breakthrough. The Cells can be operated in series or parallel depending on the test requirements. An Ellutia 200 Series GC analyses the Headspace from the cells, and the results are automatically plotted by custom software.

New Gas Chromatographs for On-line Natural Gas Analysis
The new gas analyser DynamiQ-X NG2210 from Sensirion provides fast and accurate on-line monitoring of natural gas and delivers calorific values for composition control and custody transfer purposes. Meanwhile, the DynamiQ-X NG2220 performs the same analysis for natural gas containing hydrogen at concentrations as high as 20 % using only one carrier gas. The DynamiQ-X NG2210 and DynamiQ-X NG2220 can be integrated into many locations of the natural gas infrastructure, including natural gas city gate stations, blending stations, natural gas conditioning stations, offshore systems and power-to-gas systems. With a volume of only 10 L and weighing less than 15 kg, the instruments are easy to transport and can be deployed anywhere for analyses, if local power and gas bottles are available.
The instruments can accommodate two or three gas chromatograph (GC) units working in parallel, each performing a different GC analysis under individually optimised conditions. Each GC unit contains a state-of-the-art microchip-based injector and a thermal conductivity detector (TCD) combined with a proven microbore GC column and is set with optimal chromatography conditions. This configuration enables an accurate instrument as well as a very short analysis time of less than a minute.
DynamiQ-X is designed as a stand-alone working instrument that uses an integrated processor on a future-proof platform, so that it can carry out continuous monitoring. The instrument contains an easily exchangeable GC cartridge that allows fast local maintenance. In addition, a PC can be connected to the analyser at any location via a network connection.
Sustainability and the facilitation of the energy transition are of global importance today. Qmicro by Sensirion has therefore developed the DynamiQ-X NG2210 and NG2220: as solutions to increase gas analysis capabilities and cover green gases, minimising the total cost of ownership to gas distributors. The analysers’ ability to store data for at least two years, also facilitates compliance with legislation and enables observation of long- term trends.

Versatile Portable GC
The portable GC 312 from PID Analyzers can be utilised for environmental, quality control, process & stack gas monitoring, natural gas, building & transportation security, arson & forensic applications.
Designed in its own carry case, the 312 will go anywhere with its light weight and rechargeable battery which lasts 8 hours. The 312 is pictured in the boot with an optional concentrator to achieve trace level analyses of a particular species, it has significant data storage capability in a 2 GByte smart card, and a choice of excellent GC detectors. The system can accommodate up to two detectors and additional detectors can be added and easily interchanged by the user. This GC features a large colour display and is powered by a Pentium PC with Windows® operating system and onboard PeakWorks Chromatography Integration Software.
10 (embedded)
The principle of operation is gas chromatography with a series of detectors that can be easily interchanged allowing the GC to be used for a variety of applications in the field or the lab. The detector electronics are compact and modular and the detector can be changed by removing the column, connector and two screws. There are only three sets of electronics for the four detectors, so an upgrade only requires the purchase of a second or third detector and second electronics package. PeakWorks is a dual channel system. The GC will accommodate packed (1/8” or 1/16”), capillary (0.53 or 0.32 m id) or PLOT columns by any manufacturer on a 3.5: diameter spool) and an optional heated injector is used for liquid samples. The algorithms for data processing were taken from our powerful PeakWorks program and are incorporated in the embedded software.
Photoionisation detector (PID): VOCs, aromatics, unsaturated hydrocarbons, sulphur compounds and inorganic gases (hydrogen sulphide, arsine/ phosphine, ammonia). It is an ideal detector for environmental analysis, and QC with its low ppb to % detection range; also fenceline, water, soil, field measurements.
Thermal Conductivity Detector (TCD): Hydrocarbons, inorganic & fixed gas response make this detector ideal for applications such as QC, natural gas analysis, LPG analysis, process streams, gas or liquid analysis... in the lab or field- ppm to 100%
Far-Ultraviolet Absorbance Detector (FUV): Hydrocarbons, inorganic & fixed gas response at levels 10-100 times lower than the TCD- also H2 O, O2 , N2 O at ppb to ppm levels
Flame-Ionisation Detector (FID): Responds to all hydrocarbons including methane- environmental field measurements, landfill gases, oil patch monitoring. More information online:
