Testing

Environmental Micro Analysis, Inc. specializes in pesticide residue analysis using methods developed by the EPA, FDA, and CDFA. We provide a variety of multi-residue screens and specific pesticide analyses on a variety of different matrices, some of which are, but not limited to: raw agricultural products, processed foods, plant tissues, spices, herbs, soil, and water. Please feel free to view our multi-residue screens and services to see which might be the best fit for you. If you would like help determing which of our multi-residue screens is the best fit for your needs please feel free to contact us.

Services

At EMA we strive to meet the needs of our clients. Through the years we have come to understand not all testing needs fall into the multi-residue screens listed below. We provide custom designed services catering to our clients in many industries like: Food Processors, Environmental Services, Agriculture, and Importers/Exporters.

Multi-residue screens

CDFA: A combination on three different screens Organochlorine/Pyrethroid (OC/Pyr) Screen, Organonitrate/Organophosphate (ON/OP) screen, and Carbamate (CB) screen. This grouping of tests can be requested as one single screen of your choice, two screens of your choice, or a full screen that includes all three. Our CDFA Multi-Residue Screen covers over 150 common pesticides, insecticides, herbicides, and fungicides. These screens follow the regulations and standards of the California Department of Food and Agriculture and meets or exceeds the Maximum Residue Limits (MRL's) established in 40 CFR section 180.

EBDC: This screen covers a grouping of Ethylenebisdithiocarbamates that are tested for by the conversion of the analytes to Carbon disulfide. Combined with our low detection limits and high selectivity, EMA uses a proprietary modification to the CDFA procedure that dramatically reduces false positives for EBDC's. This method is also compliant with EPA method 630.

EPA Soils and Waters: We provide numerous screens that cater to the testing of soil and water. Each screen is performed in accordance with the regulations and standards of the EPA. Please see the following list:

8081 (soil/water)
8141 (soil/water)
8151 (soil/water)
8318 (soil/water)
619 (soil/water)
630 (soil/water)
632 (soil/water)

European Union (EU) Pharmacopeia: Includes a specific list of compounds determined to be of interest from materials for pharmacological use in European countries.

FDA 402.E2: Formerly referred to as method FDA 221, FDA 402.E2 was developed to analyze chlorinated herbicides such as, but not limited to, 2,4-D, MCPA, and 2,4,5-TP.

FDA Detention Without Examination (DWE): Pesticide residue analysis for imported foods being held under the Food and Drug Administration's Detention Without Examination Program is a specialty of Environmental Micro Analysis. EMA has the expertise to guide you through the complex maze of regulations, and to prepare customized data packages for your commodity or processed food. Our experience gives your commodity the best chance of clearance through the FDA as expeditiously as possible.

FDA Import: The FDA currently screens for a variety pesticides in imported foods. EMA has closely duplicated and improved on the analytical procedures the FDA has developed in their own laboratories at low detection levels. Whether you are looking to test imported commodities prior to shipping, or seeking to avoid the Detention Without Examination program, our FDA Import Screen can help you avoid refused shipments and costly violations.

LC/MS/MS "Reduced Risk" (RR): EMA developed this screen to test for many of the newer "reduced risk" pesticides that may not have Foreign Registrations. This includes, but is not limited to, Pesticides like Spirotetramat (Movento), Spinetoram (Radiant), Mandipropamid (Revus).

LC/MS/MS Extended Screen (Ext): Our LC/MS/MS Ext Screen covers the same pesticides that are in our LC/MS/MS RR Screen, but adds many pesticides formerly analyzed by specific HPLC methods. In addition, our Extended Screen includes several Organonitraogen and Organophosphate pesticides at very low detection limits. Where before several different methods had to be employed, we can now significantly reduce the time and cost to you with our Extended Screen.

Luke: This screen is virtually identical to the CDFA screen mentioned above, and can also be split into the OC/Pyr, OP/ON, and CB screens, but follows the guidelines and regulations of the Federal Food and Drug Administration.

Sulfonyl Urea: A specific group of herbicides requiring a unique extraction and clean-up with LC/MS/MS analysis. This group of herbicides requires very low detection limits, due to the very low aplication rates.

USP 561: This is a specific group of tests and compounds the FDA has determined to be of significant interest to products within the pharmacological industry. This list also contains specific Maximum Residue Levels appropriate to this industry. EMA tests for these compounds using a wide range of instruments and detectors with significant overlap to insure the accuracy and quality of data.
