Specialty SPE

Specialty SPE for Application-Specific Cleanup

Explore Agilent Bond Elut sorbents for pigments, PCBs, mycotoxins, cis-diol compounds, and aqueous environmental samples.

Agilent Bond Elut

Specialty SPE products provide purpose-built solid phase extraction solutions for analytical workflows that require more targeted selectivity than conventional reversed-phase, ion exchange, or general polymeric sorbents. Chrom Tech supplies these specialized Agilent Bond Elut chemistries for laboratories performing environmental analysis, food testing, biochemical separations, and other sample preparation workflows where extract cleanliness, analyte specificity, and reproducibility are critical.

Within the Agilent Bond Elut portfolio, specialty sorbents are designed to solve distinct cleanup and extraction challenges. These chemistries support applications ranging from pigment removal and PCB extraction to mycotoxin cleanup, cis-diol affinity retention, and large-volume aqueous sample extraction. By matching the sorbent more closely to the sample matrix and analyte class, laboratories can improve method performance while reducing unnecessary cleanup complexity.

Bond Elut Carbon

Bond Elut Carbon is designed for cleanup of pigments in food, fruit, and vegetable samples as well as small organic wastewater residues. Agilent highlights ultrapure graphitized carbon particles and strong retention mechanisms that help remove matrix interferences while supporting cleaner extracts for downstream analysis.

Bond Elut Cellulose

Bond Elut Cellulose uses a pure microgranular cellulose sorbent with high capacity for polar compounds. Agilent notes its broad pH stability, extremely low metal content, and strong suitability for loading polar substances from aqueous and organic phases, making it useful in specialty workflows where a hydroxyl-rich polar surface is beneficial.

Bond Elut PCB

Bond Elut PCB is a specialized sorbent developed for extraction of polychlorinated biphenyls (PCBs) from various matrices. Agilent positions this chemistry as an easy-to-use option that allows analytes to be loaded and eluted using a simple single-solvent method before GC/ECD analysis.

Bond Elut Mycotoxin

Bond Elut Mycotoxin is a specialty cleanup sorbent for food extracts prior to analysis of trichothecenes and zearalenone. Agilent presents this phase as a streamlined alternative for mycotoxin workflows where efficient cleanup, good reproducibility, and practical sample throughput are important.

Bond Elut PBA

Bond Elut PBA is a unique silica SPE sorbent containing a phenylboronic acid functionality. Agilent notes that this phase retains analytes through a reversible covalent bond, giving it strong affinity for cis-diol-containing compounds such as catechols and nucleic acids while delivering high specificity and clean separations.

EnvirElut

EnvirElut sorbents are designed for extraction of a wide range of compounds from aqueous matrices. Agilent positions these sorbents as application-specific options for target analytes in environmental workflows, including formats used for pesticides, PAHs, and related sample preparation methods.

Specialty Selectivity for Difficult Methods

Specialty SPE phases are especially valuable when methods involve unusual matrix components, highly specific analyte classes, or extraction challenges that standard sorbents do not address efficiently. By using sorbents tailored to the chemistry of the sample, laboratories can improve matrix removal, simplify workflows, and support more reliable analytical results.

Chrom Tech supplies Specialty SPE solutions for laboratories that need application-focused cleanup and extraction chemistries. Whether your method requires pigment removal, PCB extraction, mycotoxin cleanup, affinity-based retention, cellulose-based polar loading, or aqueous environmental extraction, Chrom Tech can help match the right Agilent Bond Elut specialty sorbent to your workflow.

Frequently Asked Questions â–¸
What is Specialty SPE used for?
Specialty SPE is used when a laboratory needs application-specific cleanup or extraction chemistry for sample types that are not well served by standard reversed-phase, ion exchange, or general polymeric sorbents.
What is Bond Elut Carbon used for?
Agilent positions Bond Elut Carbon for absorption of pigments in food, fruits, vegetables, and small organic wastewater residues, helping produce cleaner extracts and improved recoveries in challenging matrices. :contentReference[oaicite:1]{index=1}
What makes Bond Elut Cellulose different?
Bond Elut Cellulose uses pure microgranular cellulose, is stable across a broad pH range, has very low iron and copper content, and offers strong capacity for polar compounds from aqueous and organic phases. :contentReference[oaicite:2]{index=2}
What is Bond Elut PCB designed for?
Bond Elut PCB is designed for extraction of polychlorinated biphenyls from different sample matrices, and Agilent notes that analytes can be loaded and eluted using a simple single-solvent method before GC/ECD analysis. :contentReference[oaicite:3]{index=3}
What is Bond Elut Mycotoxin used for?
Bond Elut Mycotoxin is used to clean up food extracts for improved trichothecene and zearalenone analysis. Agilent describes it as a proprietary silica-based ion exchange sorbent and notes results comparable or superior to competing methods such as immunoaffinity and charcoal/alumina columns. :contentReference[oaicite:4]{index=4}
What kinds of analytes are suited for Bond Elut PBA?
Bond Elut PBA is suited for cis-diol-containing compounds, including analytes such as catechols and certain nucleic-acid- or carbohydrate-related compounds, because the sorbent relies on reversible covalent binding for selective retention.
When would a lab choose Specialty SPE instead of a general-purpose sorbent?
A laboratory would usually choose Specialty SPE when the matrix contains unusual interferences, the analyte class requires highly specific retention, or the method benefits from a sorbent designed for a narrow cleanup task such as pigments, PCBs, mycotoxins, or affinity-based separations.
Does Chrom Tech help with Specialty SPE selection?
Yes. Chrom Tech can help identify whether Carbon, Cellulose, PCB, Mycotoxin, PBA, or another specialty sorbent is the best fit based on matrix type, analyte class, cleanup goal, and downstream analytical method.
