Case Studies

PDV6000plus

Case Study 1

Mercury onsite monitoring in soil and water samples using the Cogent Environmental PDV6000plus and soil extraction devices

This study details the onsite extraction of Mercury from a selection of soil and sludge samples and their subsequent analysis on the PDV6000plus.

Case Study 2

SENSPOL evaluation of Cadmium, Lead and Copper onsite monitoring of water and soil samples

This study details the onsite analysis of water and soil samples from 5 different locations in germany using the PDV6000plus and contains comparison data with Graphite Furnace Atomic Absorption (GFAA).

Case Study 3

Lead in Soil: Comparison of the Cogent Environmental extraction kits and PDV6000plus analysis (ASV) with inductively coupled plasma optical emission spectrometer (ICPOES) Laboratory Extraction and Analysis

This study contains data generated by Matrix Environmental when using the PDV6000plus to monitor soils for Lead and subsequent analysis of soil samples by an independent reference laboratory by ICPOES to provide comparison data.

Case Study 4

Arsenic in Bangladesh and Perth

This study details the the Arsenic problem in ground water from Bangladesh and how the PDV6000plus can be used to monitor the Arsenic levels in ground water wells. Contains comparison data with inductively coupled plasma mass spectrometer (ICPMS) for groundwater samples in Perth, Western Australia.

OVA5000

Case Study 1

Evaluation of the Cogent Environmental OVA5000 for continuous Arsenic monitoring at the Vineland Chemical Company Superfund Site

Cogent Environmental have installed an OVA5000 at the Vineland chemical company superfund site in New Jersey, USA. This site and the nearby lake and river have been heavily contaminated with Arsenic. The instrument has been installed in the wastewater treatment plant to monitor arsenic levels in the effluent from soil and groundwater remediation. This study highlights comparison data between the OVA5000 and the laboratory methods GFAA and ICPMS.

Case Study 2

Continuous Arsenic Monitoring at the Vineland Chemical Company Superfund Site

This is a follow up to Case Study 1 and details the performance of the OVA5000 during the first 6 months of operation at the Vineland Superfund site. The study contains performance data and highlights the benefits along with the increased efficiency at which the plant is able to operate.

Case Study 3

OVA 5000 Trial Report for Zinc Smelter. (For Zinc Cadmium and Lead Analysis)

The first three months operation of an OVA5000 installed at a Zinc Smelter to monitor Zinc, Cadmium and Lead in the effluent stream. Contains summary and comparison data with an ICP instrument.
