Electrical Conductivity

Written by

Electrical conductivity is the measurement of how well the water can pass an electrical current. Conductivity can be affected by the presence of inorganic dissolved solids; organic compounds do not conduct electricity very well so they have a minimal affect on conductivity. Conductivity is dependent on the temperature of the water, the warmer the water the higher the conductivity.

We can test for Electrical conductivity in our chemical laboratory in Fareham, for more information on this and all our services please fill our the form below or call us on 01329 287 777.

Bromine

Written by

Bromine is a brown/red liquid at room temperature. It is very volatile so it doesn’t occur as a liquid naturally; it is rarely found in a salt form, it is most commonly found as bromide in the ocean because of the high solubility of the bromide anion.

Envirochem offers testing for both Bromine using colourmetrics and bromide using an IC.

Total Organic Carbon

Written by

Total Organic Carbon is the measure of how much organic carbon there is in a sample. TOC is often analysed by finding the total amount of carbon in a sample and then finding the ‘inorganic carbon’, the amount of carbon dioxide and carbonic acid salts, and then subtracting the IC value from the TC value. This is a requirement for WAC certificates and can give you an idea of the amount of hydrocarbons. Inert waste has a TOC limit of 3%, stable and non-reactive non-hazardous waste has a limit of 5% and hazardous waste has a limit of 6%.

Water Effluent Suite

Written by

The most commonly requested suite of water analysis is our effluent water suite. This includes suspended solids, ammonia and biological oxygen demand (BOD) and is often carried out on the inlet and outlet sections of water treatment systems to check the efficiency of the process.

In addition to tests required to satisfy Environment Agency (EA) guidelines, we can also accommodate testing requests to meet extra guidelines set by individual local authorities, such as testing for pH, metals, anions and organics. We can also look at the particle size of the suspended solid to determine the correct size of filter needed to remove it from the water.

Phosphate – Ion chromatography

Written by

Phosphate is a good compound to have in soil as it helps plants grow and is commonly found in fertiliser, its availability may govern the rate of growth of plants. We test for it using an Ion chromatography. High levels of phosphate are good for topsoil, but it does not have a limit for WACs, effluent and processed water. Phosphate is an important component in the structure of DNA, it forms the backbone of DNA by bonding with sugar molecules. Phosphate is the most soluble form of phosphorus in water.

We offer testing for a range of Anions

Written by

Chloride is the anion of Chlorine and is very soluble in water; it is an important part of sea water and table salt. Chloride is often tested for in various water and soil samples, residues after fires and in concrete water.

When plastics burn in the event of a fire they can produce chloride. The chloride can then settle on surfaces, such as concrete, it then absorbs water and creates a corrosive substance that can attack the structure of the building.

We also offer testing for other anions such as Fluoride, Nitrate, Nitrite, Bromide, Phosphate, Sulphate and Sulphide.

Envirochem offers a large range of colourimetric testing

Written by

Envirochem offers a large range of colourimetric testing including ammonia, COD (chemical oxygen demand), cyanide, free and total chlorine, and more.

Ammonia is tested for largely because the amount of ammonia in waste water must fall under a certain limit for it to be disposed of safely into the environment. Most of our samples for Ammonia come from water treatment plants, companies testing their water discharge and from care homes that have their own water treatment facilities.

Please fill out the form below for more information on this service and our other services.

Metal content analysis for landfill acceptance

Written by

Recently at Envirochem we have noticed that more and more landfills are requesting additional testing along with the normal Landfill Waste Acceptance Criteria test (WAC test or Leachate test). Typically these include: metal content of air dried sample, speciated TPHs (total petroleum hydrocarbons, either as banded or aliphatic/aromatic split) and speciated PAHs (polyaromatic hydrocarbons).

Envirochem laboratories offer these services to their clients; therefore, we would advise contacting the landfill site or waste receiver to check if the additional analysis is required to save you time. We will always retain samples for a period of time and can carry out additional testing at short notice.

If you would like to contact Envirochem regarding our services please fill out the attached form or call us on 01329 287777

New GC-MS and GC-ECD

Written by

New GC-MS and GC-ECD

Our laboratory now boasts a new Gas Chromatograph – linked Mass Spectrometer (GC-MS) and a new gas chromatograph with electron capture detector (GC-ECD)

These two new instruments both increase and update our laboratories capabilities.

The new GC-MS is more sensitive and is equipped with a splitter allowing one injected sample to be separated on the column and then analysed by mass spectrometry for polyaromatic hydrocarbons (PAHs) as well as simultaneously being analysed for petroleum hydrocarbons (TPH, mineral oil).

The PAHs are tested either as total or speciated (EPA 16), similarly the hydrocarbons are tested as total or speciated or banded (CWG banding with aromatic / aliphatic split)

This new GC-MS / FID is therefore allows two analyses to be run at the same time on the same sample. Doubling our throughput, and reducing turnaround times for both soil and water extracts.

The new GC-MS also allows more rapid analysis of Coal Tar samples.

New method development is under way on the GC-ECD that will allow massively improved detection limits for Polychlorinated Biphenyls (PCBs) and pesticides in water.
