Welcome Jamie Fox!

Jamie_FoxWe are thrilled to announce that Jamie Fox joined Brooks Rand Labs as our Technical Sales Manager. As a key member of our Business Development team, Jamie is responsible for identifying and capturing new opportunities that require trace metals and metals speciation testing. He works closely with our business development and project management teams to ensure that the client’s objectives are met and the best possible analytical solution is selected for each project. With eight years of experience in environmental and pharmaceutical laboratories as an analytical chemist and another eight years as a laboratory auditor and data validator, Mr. Fox has the breadth of technical knowledge and experience to assist our clients with their most challenging projects. Despite the fact that he is often seen out on the road at conferences and meetings, he still loves to travel in his spare time with his wife, hang out with his two rescue hounds, or take a hike in the mountains near his home in Albuquerque, New Mexico.

Welcome Jamie!

BRL on the Road Again…

DOECAP Analytical Services Program Workshop

US-Department-of-EnergyMichelle Briscoe, BRL’s President/CEO and Jamie Fox, BRL’s new Technical Sales Manager, will be headed to Charleston, South Carolina, September 14-17, to attend the Department of Energy Consolidated Audit Program (DOECAP) Analytical Services Program Workshop. Ms. Briscoe will be presenting a talk at the workshop on the topic of Methods for the Analysis and Speciation of Mercury. BRL is a DOECAP-audited laboratory available to perform specialty trace metals analytical services at all US DOE sites and maintains a current Radioactive Materials License. Contact us for more info!

AOAC International Annual Meeting
AOACJoin Michelle Briscoe and Russ Gerads, BRL’s Business Development Director, at the AOAC 129th Annual Meeting & Exposition in Los Angeles, California, September 27-30. Ms. Briscoe will be chairing the session Analysis of Metals and Metals Speciation in Food on September 28th, and Mr. Gerads will be presenting a platform presentation in this session titled, “Analysis of Wine for the Characterization of Inorganic Arsenic and Metalloid Compounds”. Ms. Briscoe will be presenting a poster on September 29th titled, “Determination of Heavy Metals in Food: AOAC First Action Method 2015.01,” as well as chairing the meeting of the Metals Subgroup of the AOAC Contaminants Community. The full preliminary program for the conference can be viewed online. If you would like to arrange a meeting with either attendee during this conference, please contact us.

Sequential Extraction for Arsenic Speciation in Soils

Hands holding soilIt has become increasingly common for risk assessment and treatability studies to require arsenic speciation data to determine the potential mobility of this toxic contaminant at varying sites.

Looking at arsenite [As(III)] and arsenate [As(V)] values can be helpful for these studies; however, this approach can only provide a snapshot of how much arsenic is readily leachable at any given time. In situ, the conditions in soil and sediment samples can change over time depending on many factors, including the amount of rainfall, contaminant plume movement, and the hydrogeology at each individual site. Arsenic trapped in various mineral phases can be mobilized under varying site conditions, and even the treatment technologies used to remediate a site can affect the chemistry of the targeted environment and the subsequent arsenic lability.

At Brooks Rand Labs (BRL), we have a proprietary procedure for the selective sequential extraction of groups of arsenic species in soluble, adsorbed, and precipitated forms of arsenic compounds in soils, sediments, and similar solid matrices using a series of solutions with an increasing ability to solubilize and extract the solid-phase arsenic. Rather than identify specific arsenic species, the arsenic is fractionated in accordance with its interaction with iron oxyhydroxides, manganese oxyhydroxides, aluminum oxides, and other substrate components. The applied extraction solutions are designed to target the different substrate components and stabilize the respective arsenic species within each of the defined fractions below. The typical arsenic compounds listed for each fraction are only representative of how the method can perform and will fluctuate with different sites and conditions.


The BRL arsenic sequential extraction method accompanied by analysis of each fraction for total arsenic and other elements can be a powerful tool to help predict how much arsenic will be mobilized under different conditions. This type of information can be of enormous value for modeling, risk assessment, and design/engineering of treatment technologies.
