Separations is a fundamental scientific discipline focused on the isolation and purification of components from mixtures. Through techniques such as chromatography, distillation, and filtration, separations scientists separate substances based on their physical or chemical properties. This field plays a crucial role in various industries, including pharmaceuticals, food and beverage testing, environmental science, materials research, and more. Explore how separations techniques enable precise analysis, quality control, and the development of innovative products.
Bond Elut PPL is a styrene-divinylbenzene (SDVB) polymer that has been modified with a proprietary nonpolar surface. PPL will retain even the most polar classes of analytes, including phenols. The large particle size allows ease of flow for viscous or particulate-rich water samples, while the high surface area and strong hydrophobicity ensure reproducible extractions with high recoveries upon elution.
Bond Elut SAX is a strong anion-exchange sorbent ideally suited for the extraction of compounds, such as carboxylic acids, which may not retain effectively on weak anion-exchange sorbents.
Bond Elut SCX is a strong cation exchanger with a very low pKa. Although the pKa is similar to Bond Elut PRS, the presence of the benzene ring in the functional group increases the potential for nonpolar interactions. This nonpolar characteristic becomes particularly important when conducting ion exchange from aqueous systems, where selectivity towards compounds exhibiting cationic and nonpolar character is seen.
Native silica is generally regarded as the most polar SPE sorbent available. Bond Elut SI is particularly effective at separating compounds with a very similar structure. Applying the analytes in a non-polar solvent, then increasing the solvent polarity by increasing the concentration of a polar modifier, such as THF or ethyl acetate, delivers effective separations.
Simplify sodium sulfate mediated drying steps by using cartridges prepacked with ACS grade, granular anhydrous sodium sulfate. Available in three formats (LRC, Bond Elut Jr, and straight barrels).
The same Bondesil sorbent packed into the industry-leading Bond Elut cartridges is available in bulk for large-scale purification or packing custom cartridges.
Chem Elut is an economical Supported Liquid Extraction choice, available in buffered and unbuffered configurations. Agilent SLE products use a broad-performance inert diatomaceous earth sorbent for rapid, general sample preparation
Empore extraction disks provide a high flow rate solution for large volume sample preparation, and are available in a variety of bonded phases. The Empore disks are available in two diameters, 47 and 90 mm. By increasing the diameter of the disk used, the disk surface area available for sample passage increases, resulting in better solvent flow rates through the disk.
EnvirElut sorbents are specially designed for the extraction of a wide range of compounds from aqueous matrices. EnvirElut herbicides, PAHs, and pesticides are available in standard SPE straight barrel cartridges, which can be used on conventional Vac Elut vacuum manifolds.
Hydromatrix is a high purity, inert diatomaceous earth sorbent available as bulk material, offering end user flexibility and an excellent diversity of applications.
Mega Bond Elut Flash cartridges offer excellent levels of performance and productivity for the purification of organic compounds, but also for scale-up, solid phase extraction. Prepacked, disposable cartridges offer greater convenience than glass columns that must be washed, dried, and repacked after every sample.
Bond Elut SPEC is a monolithic sorbent bed manufactured with ultraclean polypropylene plastic and bonded-silica impregnated on a glass fiber disc, resulting in an SPE product that delivers faster sample processing and lower costs.
Process up to 20 Bond Elut Cartridges at the Same Time Engineered to increase laboratory productivity, the corrosion-resistant Vac Elut 20 allows simultaneous processing of up to 20 Bond Elut cartridges. The manifolds clear glass base allows careful monitoring of the entire sample collection process. Its compact, linear design requires very little bench space.
For Larger Elution Volumes The Vac Elut 20 with a large glass basin and collection rack accommodates larger 16 x 150 mm test tubes. The same high quality material and features on the standard Vac Elut system are incorporated on this special unit. These collection vessels can be utilized in combinatorial chemistry applications using large boiling tubes for collection of purified synthesis mixtures, or for any SPE extractio…
Process up to 24 SPE Cartridges at the Same Time The Vac Elut SPS 24 allows you to process up to 24 SPE cartridges simultaneously. Like all Vac Elut manifolds, the SPS 24 is made from durable, solvent-resistant materials and engineered to last. The glass sides allow easy viewing of the entire sample collection process.
Manifolds and Accessories Agilent manifolds and accessories complement the quality of SampliQ sorbents. Flexible configurations and availability as complete assemblies or individual components mean that the user has the necessary capability at any stage from method development to high-throughput operation. A full selection of adapters allows stacking cartridges for multi-step separation of or use of flexible cartridges on 12…
Agilent now treats each premium 11mm inlet septa to eliminate sticking in the GC inlet. With our premium non-stick septa, you'll never have to scrape bits of septum out of your inlet. Agilent's premium septa also have a recess on the injection side, to guide the syringe needle to the same point with every injection.
Economy Indicating Moisture Removal Traps Agilent Indicating Moisture Traps are designed to remove water, oil, and organics from gases employed in, but not limited to, gas chromatography. Refillable moisture traps are constructed from Lexan brand polycarbonate tubing. Lightweight, chemically resistant and of superior strength when compared to traps manufactured from acrylic. Agilent Indicating Moisture Traps have become the…
Agilents Precision Gas Flow Meter is the ultimate gas flowmeter for chromatography applications. This handheld flowmeter incorporates industry leading performance and features in a highly accurate and reliable package. The inherent stability of the rugged, solid state components allows us to provide the longest calibration interval on the market, all traceable to NIST standards.
The Renewable Gas Purification System from Agilent not only traps large quantities of contaminants and lasts a long time, but it is also recyclable.
Frustrated with leaky, hard to use press-fit connectors? Now anyone in your lab can easily connect guard columns or retention gaps to GC columns by using Agilent Ultimate Union kits.
Extra large gas purifiers (750 cc) are ideal for bulk purification applications or where several instruments are plumbed from a single gas source. They provide a low cost alternative to UHP grade gases. We construct each trap from one piece of heavy walled aluminum tube to eliminate potential leaks due to faulty welds. The moisture and hydrocarbon models can be refilled. The big oxygen traps must be replaced, but we offer indi…
Agilent's Direct Connect Liners provide maximum recovery and minimal decomposition of active compounds for methods requiring splitless injection, such as EPA 8270.
The ion source operates by electron ionization (EI) or chemical ionization (CI). The sample enters the ion source from the GC/MSD interface. Electrons emitted by a filament enter the ionization chamber, guided by a magnetic field. The high-energy electrons interact with the sample molecules, ionizing and fragmenting them. The positive voltage on the repeller pushes the positive ions into the lens stack, where they pass throug…
