Introduction

Analytes and Analytical Methods


The following analytes are measured in some or all of the foods in the current TDS program. The links in the table below will display a list of specific compounds included in the TDS in that class of chemicals.

The last column in the table below indicates the market baskets (MBs) since 1991 in which the analyses were conducted. The MB number (e.g., 92-2) indicates the fiscal year and the specific collection (1 through 4) for that year.

Refer to the food/analyte matrix to determine which TDS foods are analyzed for each analyte group.
