QROS Limited

QROS Limited

QROS hires on-site chemical analysers for soil and groundwater to consultants, regulators and remediation contractors. QROS manufactures the world leading hydrocarbon analyser the QED HC-1 but also provides the latest technologies for on site analysis for Heavy Metals, Chlorinated Solvents, PCB`s, Pesticides, and many other target contaminants. Environment Agencies around the world endorse the use of on-site analysis to maximise efficiency and improve the overall quality of the analytical data generated. QROS products used on projects worldwide have shown how generating rapid and accurate results on site really are the best practice for managing SI and Remediation activites. Please contact QROS and let us show you how on site analysis gives significant project cost savings while improving data quality and reducing uncertainty.

QROS was established in 2004 to provide a single supplier of accurate on site analysis techniques that could generate rapid and reliable results for contaminated land practitioners, waste management operators and regulatory authorities. Good quality on site analysis when used appropriately can increase the overall quality of the analytical data being generated for a site as well as reduce the overall site investigation or remediation cost. The availability of analytical data within minutes of taking a sample means a site investigation team can track where pollutants are in a single visit and not require multiple visits. During the remediation, soil that is uncontaminated is not needlessly excavated and sent to a hazardous or non hazardous landfill or treatment process.

The use of on-site analytical techniques has been endorsed by regulatory bodies since 1990. The US EPA had many on site methods incorporated into the SW-846 approved analytical methods guidance document. The Environment Agency in the UK also endorses the use of on site analysis as do the Australian EPA. The biggest barrier to the use of on site analysis has been the ability to get the kits or analysers to generate good quality data in the field. Good quality analysis from a reputable laboratory requires a team of staff that includes the technician who operates the instrument, an analyst to interpret the data and another technician who can maintain the analyser. The same requirements were needed when running the older generation of analyser on site, where the role of the technicians and analyst had to be combined into one person. This level of expertise is unusual in one person and if a person is not sufficiently well trained and experienced in the use of a technique, the results produced can be misleading. Unfortunately, many test kit and analyser manufacturers indicated that their products were easy to use and did not really require a trained operator, when in reality, a lot of training and practice was needed to get the best results. Hoping to hire a test kit or analyser and run it the next day by just reading the instruction manual has lead to many very expensive mistakes.

The latest analysers such as the QED HC-1 from QROS have been designed to be simple to operate and use the power of artificial intelligence to talk the user through the procedure and identify any problems with the functioning of the instrument or actual analysis. It is now possible to get reliable, repeatable and accurate data even from 1st time users.

We would still recommend watching the training video however before starting out

To effectively use on-site analysis, techniques must also be available to analyse for all of the contaminants expected on the site. QROS has access to the latest technology and provides bespoke software that makes data capture and manipulation much faster and simpler for all the analysers it supplies.

One final issue that is crucial to effective use of on site analysers is a readily available back up for the analyser if the one on site stops working for some reason (normally a breakage). On-site analysers are expensive and needing to keep a replacement just in case is prohibitive for many. QROS however removes these problems by ensuring 1st class technical support and back up analysers are available


A secondary issue with the older on site analysers is that they are adaptations of existing instruments or techniques often over 20 years old, and are not specifically designed for on-site analysis for contaminated land. For this reason QROS has heavily invested in its own development programme to design and build instruments and develop techniques specifically for on-site use. The first of these products is the QED HC-1 hydrocarbon analyser.  This unique analyser is able to easily identify the sample hydrocarbon type and therefore accurately quantify total BTEX, total GRO, total DRO, total PAH and BaP, all in a single analysis. QROS also works closely with other technology manufacturers to help them produce products more readily tailored to contaminated land analysis. The QROS development team is purely focused on developing new techniques and field analysers.

Based on their experience and success on other projects in 2007 QROS was asked to conduct all the screening of contaminated soil on the Olympic Park enabling project. QROSs involvement was instrumental in seeing the project move three months ahead of schedule. 

Due to the success of QROS in the UK, 2008 saw the launch QROS US. It has rapidly been involved in a number of large projects and secured the retention of on-site analytical services by several large US engineering and environmental consultancies as well as the US Navy. In June 2012, the US state of North Carolina approved the QED hydrocarbon analyser as a replacement for the method 8015 Gas Chromatography method for managing site investigation and remediation projects  involving Leaking  Petroleum Fuel storage tanks. Several other states are also looking to approve the QED analyser, showing how regulators are understanding the advantages the latest generation on site analysers can bring to reducing costs and increasing the number of successful remediations.

QROS is also establishing operations in Nigeria and Australia with the QED analyser being approved by the Nigerian Oil Spill Detection and Response Agency (NOSDRA) to help clean up oil spills in the Niger Delta.
