UV Vis spectrophotometers score with cost effi ciency and highest level all along the line
IN NEED FOR QC TESTING?
Thirsty for clean water?
Hungry for food safety?
Want a safe environment?
Anyone who is involved daily in clarifi cation, measurement and analysis technology with standard- compliant routine checks of water quality needs reliable and, above all, economical equipment. It is even better when everything comes from a single source: high-quality test equipment, cost-effective reagents, advanced problem solutions, service and know-how. With the XD7000 VIS and XD7500 UV/ VIS spectrophotometers from Lovibond®

Handbook of
Methods the instrument starts each method automatically. In addition, the XD series has automatic cuvette recognition for the most common cuvette sizes and shapes. Simply place the cuvette test in the measuring shaft: The appropriate test method starts automatically. With the external scanner, the barcodes can also be read directly from the reagent packaging or from the Handbook of Methods. 160 pre-programmed methods are available – also for integration into your own work instructions. The reagents also come directly from Lovibond® service paths, lower acquisition and operating costs.
, anyone who needs laboratory quality for reliable measurement
, most of them from the company’s in-house production. This means: short ordering and
The high-quality reference beam technology guarantees highest accuracy. The instruments also support the user in analytical quality assurance including Good Laboratory Practice (GLP). Optionally, the complete spectrophotometer can be checked in connection with the method or the interference-free determination of ingredients in the sample. Everything is automatically protocolled. A scheduled quality check is no problem with fi xed test intervals. Up to three user levels are possible. User-defi ned methods can be set up, polynomial data/coeffi cients can be taken over from other devices and the measurement data can be transferred with a few simple steps.

Mercury in Ambient Air, Workroom Air and Stack Gas Applications
Currently the monitoring of mercury in ambient air is not extensive due to the limited number of monitoring sites around the globe. In one approach P S Analytical (PSA) has used gold on silica Amasil adsorption tubes designed for pumped mercury vapour sampling as passive samplers, offering a simple, maintenance free and cost-effective sampling solution. These tubes are returned to a centralised lab for thermal desorption and analysis by Atomic Fluorescence Spectroscopy (AFS). These sampling tubes may be reused and redeployed.
Workroom air monitoring requires a different sampling approach. There is often the potential of high concentrations of mercury vapour in localised areas, e.g. during Hg recovery/recycling or in manufacturing processes. Real time results are required to protect workers from potential Hg vapour exposure. PSA’s approach here is for the workroom air to be pumped to a central AFS instrument. Multi-stream (room/area) monitoring is therefore easily achieved, offering early warning alarms should set limits be breached.
Stack gas monitoring is usually carried out for emission compliance and typical industries affected include; coal fi red power, cement manufacture, smelting operations and the like. Here a coated sample probe takes a volume of stack gas, dilutes and removes interference before carrying it to the AFS for determination.

In common with all our technology PSA employs AFS as our central analytical technology which offers dominance and leading performance in terms of; sensitivity, working ranges, freedom from interferences. These attributes combined with our novel sampling systems, our hallmarked robustness and ease of use make PSA your fi rst choice for mercury determinations.

New technology expands applicability of headspace and SPME analyses for food and
environmental samples Markes International has announced that it has entered into an agreement with ExtraTECH Analytical Solutions to globally sell ExtraTECH’s newly developed and patented vacuum-assisted caps for headspace microextraction.
The caps ingeniously extend the applicability of headspace, SPME and SPME Arrow sample extractions by allowing analytes to be extracted under vacuum conditions with milder heating and agitation than is required using current non-vacuum methods. This avoids the risk of sample degradation and therefore produces a more representative sample profi le with much higher extraction sensitivities – an obvious benefi t to all analyses.
Furthermore, extraction times are typically reduced by half when extraction by vacuum is used, because it lowers the initial pressure in the vial, thus greatly reducing the gas-sample phase resistance, resulting in a much faster transfer of mass analytes to the headspace. Naturally, this translates into signifi cant productivity gains for laboratories – especially those which are high throughput, as is the case within food and environmental sectors, for example.
Rachael Szafnauer, product marketing manager of Markes’ sample extraction product lines, said: “The caps unlock the full potential of headspace sampling, allowing fast extraction under mild conditions, and they’re completely re-usable too. All labs need to do is wash and recondition them. So, they reduce waste, time and energy costs.
“We’re very excited about how the caps enable analysts to benefi t from enhanced extraction capabilities. ExtraTECH’s technology is a great fi t with the Markes’ sampling technologies and its Centri instrument portfolio and we’re looking forward to working closely with our customers, helping them to adopt this breakthrough technology.”
ExtraTECH’s founder, Elia Psillakis commented: “Our long-standing collaboration with Markes has been driven by our shared passion, determination and commitment to innovation. Now we have brought vacuum-assisted extraction technology to market, I am convinced that our products and methods will benefi t laboratories worldwide.”
