xiv UK Focus - Environmental Laboratory Rapid Direct Mercury Analysis in Soil Samples


The DMA-1 and DMA-80 mercury analysers from Milestone offer a rapid solution to the growing challenge of detecting mercury levels in soil. The increased presence of mercury in our soils, thanks to industrial processes, the burning of fossil fuels and the use of pesticides, has increased the need to monitor mercury levels in soil and sediment.


Contaminated soil must be excavated and remediated, or depending on the level of contamination, disposed of as hazardous waste.


It’s a time-consuming process, but the Milestone DMA-1 and DMA-80 direct mercury analysers, distributed in the UK by Analytix, help laboratories in the food industry to optimise their mercury analysis processes.


The DMA-1 is a manual single analysis system that is designed for laboratories with low sample throughput. The DMA-80 is an automatic sample analyser with capacity for 40 samples, designed for larger workloads.


GAS PUMPS LIQUID PUMPS


Neither system requires any sample preparation prior to analysis thus eliminating the risk of mercury loss and cross contamination. This also means ease of use, low running costs, and no need for handling and disposal of hazardous chemicals. In addition both systems have the advantage of ‘running on air’ that removes the requirement for in-house or bottled gases.


The DMA-1 and DMA-80 have been used to develop the US EPA method 7473. They are also compliant with ASTM D-6722-01 and ASTM D-7623-10.

Traditional SPME fiber technology has some significant drawbacks including poor mechanical stability and a small phase volume. The Restek PAL SPME Arrow system is a revolutionary change in microextraction that combines exceptional robustness with faster extraction times and trace-level sensitivity. In contrast to traditional SPME fibers, SPME Arrows contain significantly more phase volume, which allows more target analyte to be extracted in less time, significantly increasing sample throughput. In addition, the stainless steel construction, unique Arrow tip, inner stabilising rod, and outer sheath design fully protect the phase, minimizing both analyte loss and mechanical damage. Use with our new SPME test mix to ensure performance after each installation. This mix is a certified reference material (CRM) with verified composition and stability.

KNF’s NEW MICRO DIAPHRAGM GAS PUMP - NMP 03 offers outstanding performance in terms of power consumption, suction speed and linearity. Ideal for medical and safety-related applications.


For More Info, email: email:


Measuring only 12.9 x 21.4 x 24.2 mm (with brushless motor), KNF’s latest diaphragm gas pump is setting new standards when it comes to compact design. The NMP 03 is also truly lightweight (starting at 11 g). This makes the pump’s performance data even more impressive. At a constantly linear rate, the pump can transfer quantities from just a few millilitres up to 500 ml/min. Pumping small quantities of air in a controlled manner has never been so simple.


Troublesome pesticides can be analysed more easily and accurately with single- compound standards from Restek. We’ve just added a new pyrethrins CRM to our inventory, so individual reference standards are now available for dicofol, metribuzin, bromacil, lenacil, dodine, anilazine, captan, folpet, and pyrethrins. Use these standards to simplify method development, establish instrument detection limits (IDLs), verify performance, test stability, and resolve degradation issues. Isomeric in nature, the pyrethrins neat material contains the following isomers: cinerin I and II, jasmolin I and II, and pyrethrin I and II. Isomer ratios for each lot are given in elution order on the certificate. Restek is your one- stop shop for accurate, reliable pesticides analysis. We are the only reference standard provider that offers everything you need from sample prep to LC and GC columns and consumables.

New Micro Diaphragm Gas Pump is the Smallest of its Kind


KNF’s micro gas pump NMP 03 offers outstanding performance in terms of power consumption, suction speed and linearity.


Thanks to its compact size and outstanding efficiency, the NMP_03 is particularly suitable for use in portable and battery- operated devices, including handheld devices for emission measurement or drugs and explosives detection. The NMP 03 is also very well suited to use in medical devices. In laboratories, it can be employed in handheld pipette applications, for example.


The NMP 03 is extremely quiet, making it ideal for medical applications carried out in close proximity to the patient, such as wound therapy (NPWT) or patient monitoring.
