Experience & Expertise

Since 1982, Brooks Rand Labs has specialized in providing the highest quality trace metals analytical services and instrumentation. While many labs have just recently begun to offer methods for low-level metals determination, Brooks Rand Labs has been offering low-level mercury and methylmercury analytical services for over 20 years! Low detection limits, outstanding data quality, and unparalleled customer service have established Brooks Rand Labs as the premier specialty metals analytical laboratory services provider. As experts in the determination and characterization of trace metals in complex matrices, Brooks Rand Labs has the capabilities to meet even the most challenging project requirements.

Ultra-clean, pre-tested sampling equipment delivered directly, fast turn-around-time options, and custom reporting packages at competitive prices ensure that our clients receive the quality data they require to make critical decisions.

Ultra-low Detection and Reporting Limits

Brooks Rand Labs consistently strives to achieve detection and reporting limits that are among the lowest commercially available. Performance based evaluations of laboratory techniques ensure the most accurate and precise measurements at even the lowest concentrations. Ultra-clean facilities, laboratory equipment, and reagents, custom designed state-of-the-art instrumentation, and constantly improving methods allow Brooks Rand Labs to provide meaningful metals concentrations data in even the most challenging matrices.

Outstanding Data Quality

As an ultra-low level trace metals analytical laboratory, Brooks Rand Labs appreciates how important high quality data are for our clients. All our data is subjected to a rigorous multi-level review process to ensure only the most credible and scientifically defensible data is provided to our clients.

The accuracy and precision of our data are constantly proven by internal and client-requested laboratory audits; consequently, Brooks Rand Labs is proudly NELAP accredited through the State of Florida Dept. of Health and certified in many additional states.

Unparalleled Customer Service

The project management team at Brooks Rand Labs provides clients with an unparalleled level of support from initial project planning, to data validation and interpretation, and project follow-up. They review quality assurance and sampling plans, advise on sampling procedures, and produce custom reporting packages that are superior to other analytical laboratories.

Complex Matrices

Unlike many laboratories, Brooks Rand Labs has extensive capabilities to analyze low-level trace metals in even the most complex matrices.

• seawater
• industrial wastewater
• atmospheric deposition
• soil, sediment, & sludge
• plant and animal tissues
• blood, urine, & hair
• food products
• cosmetics
• ambient air
• flue gas
• coal and coal byproducts

Speciation & Mobility

Despite the growing interest in the regulatory community concerning bioavailability, Brooks Rand Labs remains one of the few experts in providing commercially practical analytical solutions for the speciation of various toxic trace metals with specific valence states or characteristics. Through advanced separation techniques, we are able to quantify arsenic, chromium, iron, selenium, and mercury concentrations in multiple matrices according to the fraction of interest, with new capabilities added regularly.

Mercury Speciation

• methylmercury (MeHg)
• dimethylmercury (DMeHg)
• inorganic mercury (Hg(II))
• acid labile mercury
• volatile or elemental mercury (Hg0)
• extractable organic mercury
• extractable inorganic mercury
• semi-mobile mercury
• non-mobile mercury

Arsenic Speciation

• arsenite (As(III))
• arsenate (As(V))
• monomethylarsonic acid
• dimethylarsenic acid
• trimethylarsine oxide
• arsenobetaine
• arsenocholine

Selenium Speciation

• selenite (Se(IV))
• selenate (Se(VI))
• selenocyanate
• methylseleninic acid
• dimethylselenide
• trimethylselenonium ion
• selenomethionine
• selenocysteine
• selenocystine
• Se-methylselenocysteine
• selenohomocysteine
• selenocystamine
• selenocystathionine
• γ-glutamyl-Se-methylselenocysteine

Chromium Speciation

• trivalent chromium (Cr(III))
• hexavalent chromium (Cr(VI))

Iron Speciation

• ferrous ion (Fe(II))
• ferric ion (Fe(III)
• acid labile iron

Custom Method Development

Often – due to a specific matrix type, analyte of interest, or required method detection limit – projects necessitate the development of custom methods in order to achieve their objectives. Brooks Rand Labs has extensive experience developing previously unavailable methods and consistently exceeds even the most rigorous requirements and client expectations.
