   Sediment Analysis

In Ambios we have always undertaken in-house sediment analyses, often in collaboration with Sediment Analysis Services (John Malcolm). Since John's retirement Ambios Environmental Consultants now offers to clients a full sediment analysis service tailored to marine and estuarine sediment types wordwide.

    Methodology and pricing

Our simple and long-established methodologies are described in detail in the links below. Particle-size analysis for samples <1kg cost £45, larger (clamshell/Hamon) samples for accurate gravel fraction PSA cost £60 each. Organic carbon determination costs £15 per sample. Please contact us for any further clarification, prices and for advice on sample collection and sample storage.

Analysis A

Sand - Dry Sieve 4 to -4 phi, 0.5 phi interval (16mm to 63µm)

(used when sample contains <10 - 20% material finer than 100 microns)

Analysis B

Mud & Sand - Dry and Wet Sieve 4 to -4 phi, 0.5phi interval (16mm to 63µm)

(used when sample contains >10 - 20% material finer than 100 microns)

Analysis C

Pipette analysis of silt and clay particle-size (-4 to -8 phi, 63 to 4µm)

Analysis D

Organic Carbon content of silt and clay fraction (wet digestion)

Analysis E

Carbonate Content (by acid loss)

Accurate Particle-size analysis of gravel and cobble samples (large samples), using nested subsampling method 

Contaminant Analysis (samples preparation in-house, management of sub-contracted analyses)

Microscope Analysis of mineral content; heavy mineral separations.
