About the Lab

Air Quality Testing

The air quality testing service is also routinely used to monitor the air quality of a workplace and is used as a useful technique for ensuring a healthy and safe environment for employees. The air quality laboratory analyses sample tubes, badges, filters and impinge solutions for a wide range of compounds of interest in OS&H monitoring. Example of these compounds are metals ( e.g. lead, mercury), hydrocarbon solvents, benzene ( e.g. petrol station attendant monitoring), alcohols, ketones, chlorinated solvents, formaldehyde, etc.

Water Testing   

• Drinking (Potable) water testing
• Agricultural Water Testing
• Other Water Testing

Environmental Testing

General Environmental Tests
Umoya VOHE Laboratories can test: pH, alkalinity, conductivity, turbidity, suspended solids, ash, chloride, sulphate, fluoride, calcium, magnesium, hardness, sodium, potassium, silica, cyanide, sulphide, tannins, MBAS, volatile fatty acids, Dust Gauge analyses, total phenols, TCLP extraction/testing.

Nutrients

Oxygen demand
Chemical oxygen demand(COD), Biochemical oxygen demand(BOD), total organic carbon(TOC/DOC/NPOC)

Metals
Umoya VOHE Laboratories’ well equipped laboratory for metals and other elements routinely analyses for: aluminium, antimony, arsenic, boron, barium, bismuth, cadmium, chromium, hexavalent chromium, cobalt, caesium, copper, iron, lithium, manganese, mercury, molybdenum, nickel, lead, selenium, silver, strontium, tin, thallium, uranium, vanadium, zinc and other, Metals may be analysed as the total, total recoverable, acid soluble or dissolved(soluble)fraction.

Matrices
Soils, sediments, sludges, potable waters, ground and surface waters, effluents, leachates, trade wastes.

Other
* Anions- F, CI, SO4,Br, NO2N, NO3N, Oxyhalides
* Cations- Ca, Mg, Na, K, hardness.

Organics – hydrocarbons ( TPH, BTEX, PAH), VOC, SVOC, PCB, organchlorine, organonitrogen and organophosphate pesticides, acidic herbicides, PCP, TBT, HVDB, HVAA

Swab & Surface Sample Testing

Our Air Quality  laboratory regularly tests swab and surface samples. A wide variety of compounds can be tested for chemical and microbiological contaminants. If you are evaluating spraying, wanting to understand the nature of deposits or monitor cleaning processes we’ll have a swab and surface sample test  to meet you requirements.

Swab and surface sample testing in routinely used for:

• Surface contamination monitoring
• Evaluating spray drift
• Understanding the nature of particulate deposition
• Monitoring cleaning efficiency
• Answering a range of other monitoring questions

Analysis is routinely preformed on a range of organic and inorganic air contaminants and a wide variety of microbiological contaminants.

We are always developing new test in this area. If you can’t immediately find a surface test to meet your needs call us on the number below and we’ll discuss a development option with you.
