Lead-based paint analysis

Forensic Analytical is accredited by the American Industrial Hygiene Association (AIHA), the Environmental Lead Laboratory Accreditation Program (ELLAP), and the California Department of Health Services (Cal DHS) for performing the analysis of multiple metals by atomic absorption spectroscopy (AAS) and inductively coupled plasma - atomic emission spectroscopy (ICP-AES). We strive to exceed the quality control guidelines set forth by these organizations. The laboratory is also a successful participant in the AIHA Proficiency Analytical Testing (PAT) program and the Environmental Lead Proficiency Analytical Testing (ELPAT). The chemists at Forensic Analytical are committed to providing data which is understandable, accurate and legally defensible. Quality control is extensive at each step of the analysis and includes analyst training, instrument maintenance and optimization, analysis of spiked matrix samples, duplicates and replicates, blanks and standards, and validation studies for element and matrix all overseen by a full time in-house certified industrial hygienist laboratory director. The laboratory should be contacted prior to sampling for proper sampling media and procedures. A variety of sampling media is available for a nominal charge.

Atomic Absorption Spectroscopy (AAS)
A wide variety of inorganic elements and matrices are analyzed by atomic absorption spectroscopy (AAS). AAS is the method of choice for precise quantitative determination of single elements in air, water, soil, paint and other matrices. The laboratory's primary instruments are equipped with flame and graphite furnace analytical capability. Flame analysis is suitable for most analytes and matrices including paint, wipes, soils and air samples. Graphite furnace procedures dramatically decrease detection limits and are appropriate when testing drinking water and some elements other than lead. The laboratory also maintains a mercury analyzer with excellent detection limits for mercury in a variety of matrices. All instruments are fully complemented with microwaves, hot plates, and other sample preparation equipment.

Inductively Coupled Plasma Spectroscopy (ICP)
ICP provides the laboratory with the ability to analyze multiple inorganic elements simultaneously. This technique is excellent for detecting multiple metals in all types of matrices. ICP-AES is an effective industrial hygiene tool when investigating content of multiple metals in welding fumes, paint pigments, or water. In addition to industrial hygiene analyses, ICP-AES is the primary analytical technique used when performing regulated hazardous waste characterization, such as Cal-WET CAM 17 or RCRA 8.
