Food and beverage testing is a critical scientific practice that ensures food safety, food quality, and compliance of food and drink products. Through comprehensive analysis, food testing labs assess factors such as microbiological contamination, chemical residues, nutritional content, and authenticity. By adhering to strict regulatory standards and industry guidelines, food and beverage testing helps maintain product integrity, fight food fraud, prevent foodborne illnesses, and meet consumer expectations for safety and transparency. Explore how food and beverage testing labs play a pivotal role in safeguarding public health and promoting trust in the global food supply chain.

SDB-XC is a poly(styrenedivinylbenzene) copolymer used as a reversed phase sorbent for solid phase extraction. SDB-XC is not bonded to silica but is a 100% copolymeric particle that is spherical, porous and cross-linked. It does not exhibit the secondary cationic (silanol) interactions and pH limitations common to bonded silica sorbents, so it offers more predictable and reproducible reversed phase interaction.
SDB-RPS is a poly(styrenedivinylbenzene) copolymer that has been modified with sulfonic acid groups to make it hydrophilic. SDB-RPS is not bonded to silica but is a 100% copolymeric particle that is spherical, porous and cross-linked. The sulfonation imparts unique selectivity for organic analytes that are polar in nature, such as drugs, drug metabolites, water-soluble pesticides and pesticide metabolites. SDB-RPS is also u…
Cation-SR is a poly(styrenedivinylbenzene) copolymer that has been modified with sulfonic acid. Note that Cation-SR is not bonded to silica but is a 100% copolymeric particle that is spherical, porous and cross-linked. The functional group imparts selectivity for cationic analytes, such as primary, secondary and tertiary amines.
3M Bioanalytical Anion-SR is a poly(styrenedivinylbenzene) copolymer that has been modified with quaternary ammonium groups. Note that the 3M Anion-SR is not bonded to silica but is a 100% copolymeric particle that is spherical, porous and cross-linked. The functional group imparts unique selectivity for anionic analytes, such as Endothall, Dalpon and haloacetic acids.
The Oil & Grease Disk was specifically designed for EPA Method 1664 (N-Hexane Extractable Materials (HEM) and Silica Gel Treated N-Hexane Extractable Material (SGT-HEM) by Extraction and Gravimetry). EPA Method 1664 Revision A was approved for use in the United States and published in the Federal Register on May 14, 1999. The Oil & Grease Disk incorporates C18 sorbent particles within a hydrophobic matrix. For EPA Method 166…
Empore™ Chelating Disks provide a way to selectively remove multivalent metal cations from solutions. This selectivity can be used to concentrate metals from a sample for analysis or to isolate and remove metal interferences from a complex organic or inorganic sample matrix. In the latter case, the purified filtrate is ready for use. The chelating disk has an affinity for multivalent (primarily 2+ and 3+) transition element…
Empore Carbon Disks are designed for the extraction of volatile, highly polar, and water soluble compounds from aqueous solutions. The Empore Carbon Disk provides all the advantages of activated carbon in a compact and thin Empore Disk.
