General Analysis Services

Agricultural Testing Services
Organic wastes, such as sewage sludge, agricultural wastes and composting materials, if applied correctly to agricultural land, can have a positive beneficial effect on soil fertility and soil conditioning. 
In addition, the practice can have wider benefits in terms of reduced reliance on artificial chemical fertilizers, reduction on wastes going to landfill and habitat conservation.

While there are many benefits to the practice of applying Organic wastes to land, there are also a number of concerns regarding the practice.

The Legislation
The Scottish Environmental Protection Agency (SEPA) is currently carrying out a strategic review of the practice of applying Organic wastes to land.

The Service
Caledonian Laboratories Limited offer a range of chemical and microbiological tests for the assessment of the waste material, and the receiving soils prior to application of waste.
A standard suite of tests includes Potentially Toxic Elements, pH, availability assessments, nutrient tests(N, P, K, Mg), total organic matter and Ammonia.

Through an approved subcontractor, we can also offer a range of microbiological parameters, including TVC, EColi, Faecal Streptococci and Salmonella.

Civil Engineering Chemical Testing Services
The composition of a soil needs to be considered when designing and implementing civil engineering projects. Soils can contain materials which may react with construction materials, leading to loss of strength, instability and ultimately failure.

Caledonian Laboratories Limited offer a range of chemical testing services to assist civil and structural engineers assess the site conditions at their project.

Test Suites undertaken include:

British Standard 1377 Chemical tests;
Building Research Establishment “Special Digest 1” Chemical tests;

In addition, we can offer a range of physical tests on soils through a number of approved subcontractors.
