Our renal dialysis service provides all the relevant microbiological and chemical testing requirements to ensure that the ultrapure water required for dialysis, including hemodiafiltration, is of the appropriate standard.
- Microbiological and chemical analysis for dialysis water quality
- Microbiological testing at the required sensitivity depending on the type of dialysis
- Low level limit of detection for endotoxins <0.01 eu/ml
- Rapid turnaround options available for chemical testing
Validation Kits for endoscope reprocessors (AERs – Automated Endoscope Reprocessors)
Our endoscopy validation kits have been designed to simplify on-site testing. All of the components for validation are included and have been tested to work together accurately. A full range of logistics solutions ensure representative results.
Kits contain elements required to complete on-site testing:
- Disinfection efficacy surrogates
- Self-disinfection test surrogates
- Test soils
- Pre-labelled bottles
- Other consumables as required
- Customised kits available
- Annual and quarterly validation kits available as required
- Validation kits delivered/collected from site
- Kits provided in line with HTM01-06, ISO 15883, WHTM 01-06
Cardiopulmonary Bypass and ECMO - HCUs testing
We can offer a tailored analytical service to meet the requirements of the Public Health Guidelines published in November 2015 entitled “Infections Associated with Heater Cooler Units Used in Cardiopulmonary Bypass and ECMO Information for healthcare providers in England”.
Among other testing requirements, we are able to offer quantitative detection of Mycobacteria species in water used in clinical applications; enabling the management of the risk of infection generated by Mycobacteria species including M. intracellulare or M.chimeara part of the M. avium complex which have been shown to be a potential risk in heater cooling units.
There are 4 main WAC suites, the Full Suite, Inert Suite, Stable Nonreactive Hazardous Suite and the Hazardous Suite. The Full Suite as the name suggests covers the testing required for the other 3 suites. These suites are carried out at our lab in accordance with BS EN 12457.
- Total Organic Carbon
- Loss on Ignition
- PCBs (7 Congeners)
- TPH (C10-C40)
- ANC (pH4)
- ANC (pH7)
- Phenol Index
- Dissolved Organic
Leachate LS2 and LS10
- Total dissolved
This group of organic compounds is of increasing concern in the environment due to their persistence, toxicity, and bio accumulative properties (PBTs), with a high potential to significantly affect human health. They cover a range of chemistries, but are often grouped into pesticides, herbicides, industrial by-products and health care products. They are referenced in several legislative documents such as the Water Framework Directive (WFD), the Groundwater Directive, the Industrial Emissions Directive and the Waste Directive (WM3).
There are currently 48 compounds on the Priority Substance (PS) list, although this includes three metals (mercury, cadmium and lead), and a Watch List exists whereby additional compounds may be added, once sufficient data is available.
- Brominated diphenylethers
- Chloroalkanes C10-13
- Tributyltin compounds
- Hexabromocyclododecanes (flame retardant)
The toxic concentration of these organic compounds is often very low, and therefore detection limits need to correspondingly lower. The instrumentation now implemented and validated at our lab utilises a combination of GCMS and LCMS.
- GCMS Target Based Screening – full scan mode using Deconvolution Reporting Software (DRS) to identify over 1000 compounds, including all compounds in the WFD.
- LCMS triple quadrupole – validated for acid herbicides down to ppt levels.
- GCMS triple quadrupole – validated for key pesticides, including chlorinated and phosphorylated pesticides, plus triazine, again down to ppt levels
