Environmental monitoring and testing assess the quality of our air, water, soil, and overall ecosystems. Using advanced technologies and analytical methods, environmental scientists collect and analyze samples to measure levels of pollutants, contaminants, and other factors impacting environmental health. By monitoring changes over time and identifying potential risks to human health, this field plays a vital role in informing policy decisions and implementing effective mitigation strategies. Explore how environmental monitoring and testing contribute to safeguarding our planet's well-being and promoting sustainable development.
200A pore size; available in 3.0 and 4.6 mm ids, and lengths from 50 - 250 mm. Pursuit columns are ideal for pharmaceutical applications using LC/MS, from analyzing lead compounds and biological samples in drug discovery, to implementing dependable analysis of raw materials and approved drugs in the QC process. Build on the large 200A pore size silica, high liquid density delivers up to 40% faster separations without sacrif…
The Thermo Scientific Dye Terminator Removal Kit is designed to perform the essential removal of unbound fluorescently-labelled dideoxy-ribonucleotides (ddNTPs) and excess salt from sequencing reactions prior to sequence analysis. The kit includes a 96-well plate containing pre-hydrated gel separation matrix consisting of spheres with uniformly sized pores. Sequencing reactions are passed through the separation matrix, which r…
The Thermo Scientific Separation Plate can be used for gel filtration applications (eg. dye terminator removal) when a suitable matrix is added. Features • 96 wells containing polyethylene frits, pore size of 30–45µm • 0.6ml well volume • Ready-to-use microplate format • Suitable for centrifugation
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.
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.
