At Dawn Scientific, we provide all types of SPE (Solid Phase Extraction) adsorbents suited for the exacting needs of modern analytical chemistry laboratories.
The premium-grade adsorbents, including the well-known CHROMABOND® products from Macherey-Nagel, ensure sample purification, enrichment, and cleanup with robust accuracy for multiresidue methods used in:
SPE adsorbents are a type of sorbent used in solid phase extraction where exposure to an extracting fluid results in selective partitioning of a specific analyte or analytes from a mixture.
These sorbents function based on primary interactions, including:
This enables the separation necessary prior to analysis performed by HPLC, GC, or LC-MS.
Choosing the right solid phase extraction sorbent influences biological fluids, water samples, and food matrices through reproducibility and accuracy.
Dawn Scientific offers a broad inventory of CHROMABOND® SPE adsorbents with:
– Great for non-polar to moderately polar compounds; commonly applied in pesticide, drug residue, and environmental contaminant analyses.
– Offer varied hydrophobicity for fine-tuned separations.
– Enables pi-pi interactions for the separation of aromatic analytes.
– Used for the extraction of polar analytes from non-polar solvent systems.
– Utilized for the detection of polar pesticides in food and environmental samples.
– Strong sorbent for removing fatty acids and organic acids from food extracts.
– Designed for strong anion and cation exchange, respectively, and used for charged molecules in aqueous matrices.
– Specialty SPE adsorbents that provide control over basic and acidic impurities.
– Separates compounds difficult to separate by normal or reverse phase, such as sugars and amino acids which are highly polar.
– Dual-functional sorbents useful in pharmaceutical and chemical analysis.
Dawn Scientific differentiates itself from competitors by offering special benefits such as:
Our materials for solid phase extraction are suitable for various industries and applications including:
– Biomolecules purification, sample preparation, and drug impurity removal processes
– Water and soil analysis for pesticides, PAHs, and heavy metals
– Extraction of vitamins, preservatives, and other suspicious compounds
– Purification of Blood, Plasma, and Urine samples
– Screening and detection of drugs and their metabolites
With a few easy steps, you can browse all of Macherey-Nagel CHROMABOND® SPE adsorbents we carry.
Because we keep our customers well-informed about our stocks and deadlines, you can always trust us on shipment.
This way, you don’t have to spend hours sifting through untrustworthy sites that sell other adsorbents.
Precision, purity, and performance—these are the hallmarks of the solid phase extraction sorbents we offer. Whether you need C18 for reversed phase separation, ion-exchange sorbents for charged molecules, or normal-phase adsorbents for polar compounds, Dawn Scientific has the right solution for your analytical needs.
SPE (Solid Phase Extraction) adsorbents are used to isolate and concentrate analytes from complex matrices in samples. They are commonly applied in pharmaceutical, food safety, clinical, and environmental testing.
Dawn Scientific offers a wide range of CHROMABOND® SPE sorbents from Macherey-Nagel, including C18, C8, CN, NH2, PSA, Florisil, HILIC, and more to meet various separation needs.
Choosing the right SPE adsorbent depends on your sample type and the analytes you’re targeting. Reverse-phase (C18, C8), normal-phase (Florisil, Diol), ion-exchange (PSA, NH2), and specialty sorbents (HILIC) are available for different chemistries.
Yes, many CHROMABOND® SPE sorbents are compatible with both manual and automated solid phase extraction systems, ensuring high-throughput and reproducible sample preparation.
Most SPE cartridges are designed for single-use to ensure accuracy and avoid cross-contamination. However, bulk SPE adsorbents may be reused under controlled lab conditions depending on the application.
Yes, Dawn Scientific offers bulk options and custom quantities for most SPE sorbents. Contact our sales team for tailored solutions.
SPE adsorbents are widely used in the pharmaceutical, environmental, food and beverage, clinical diagnostics, and chemical research industries for sample purification and cleanup.
