To ensure reproducible, robust, and reliable results, Kinetex columns are manufactured with high quality standards. Every step in the manufacturing process of Kinetex columns is tightly controlled for:

The Kinetex C18 is a well-rounded, all purpose core-shell column that produces increased efficiencies over traditional fully porous columns. Yielding remarkable chromatographic resolution, higher peak capacities, and greater sensitivity, so labs can get the most out of every HPLC or UHPLC analysis.

A common cause of high backpressure, split peaks, broad peaks, baseline noise, baseline drift, and loss of resolution is contaminants. All mobile phases contain some chemical contaminants or micro particulates, from the sample, solvent, or wear on the polymeric seals of the pump or injector. These contaminants can clog frits, irreversibly bind to columns, degrade performance, and even damage the flow cell. An easy solution, SecurityGuard is a universal column protection system designed to effectively (and inexpensively), protect your valuable columns, from the damaging effects of chemical contaminants, without altering your chromatographic results.

When contaminates and particulates build up at the head of the column or on the guard cartridges, system pressures dramatically increase. Simply replace the SecurityGuard cartridge instead of your column and you are able to regain normal operating conditions and reclaim original column performance.

MaxPeak HPS columns offer extremely inert stainless steel surfaces inside the column. This will prevent electronegative, chelating agents and negatively charged analytes from adsorbing to the inherent positive surface charges present on nonmodified stainless steel surfaces.

TORRANCE, Calif., July 20, 2023 /PRNewswire/ -- Phenomenex Inc., a global leader in the research and manufacture of advanced technologies for the separation sciences, today announced the launch of Luna Polar Pesticides HPLC column which features a proprietary phase that effectively separates cationic and anionic pesticides from underivatized food, feed, air, and water samples, fast conditioning, and delivers robust ionic pesticide analysis.

The Luna Polar Pesticides HPLC column is designed to help resolve the most common challenges food safety analysts encounter daily: robust determination of analytes due to matrices complexity and polarity, lengthy process due to the high number of injections needed for column conditioning, time-consuming sample preparation due to the need for derivatization, and the need to use separate columns (and systems) to determine both anionic and cationic pesticides from a sample.

The Luna Polar Pesticides HPLC column's versatile selectivity allows the separation of cationic and anionic pesticides from underivatized samples on the same column. The fully porous particle morphology of the column allows for high sample loading. Its unique selectivity provides high retention of polar analytes, fast equilibration, can be used in positive and negative mode, and offers 100% aqueous and organic stability. The particles' pore size of 100 has proven to be optimal for pesticide analysis, and the 8% carbon load delivers a great balance of polar and nonpolar retention.

Collaborative studies done with renowned laboratories and experienced food analysts demonstrate the robustness and versatility of Luna Polar Pesticides. Dr. Giacomo Napolitano, Lab Manager at Lifeanalytics S.r.l., stated "The Luna Polar Pesticides significantly reduced analysis time thanks to its fast re-equilibration! This column has improved our polar pesticides analyses."

The PrimeSphere series of HPLC columns are dependable, ultra-pure silica-based columns that offer an extensive variety of selectivities which are scalable from micro-bore and Fast LC dimensions to preparative and purification scale solutions. Pore size: 110A

The closest would be A2001050X020 Polaris 180 C18-A, 2.0 x 50 mm, 3 m HPLC column. I have been finding this information by going to the Phenomenex website to find the USP designation then I put those parameters into the LC Column Selector Tool

Phenomenex Inc., a global leader in the research and manufacture of advanced technologies for the separation sciences, announces the addition of two new phases in its successful Kinetex core-shell HPLC/UHPLC column family. Kinetex XB-C18 and Kinetex C8 bring the advantages of ultra-high liquid chromatography performance (UHPLC) within standard HPLC operating pressures to a growing list of applications. Kinetex core-shell technology meets researchers' need to improve results and increase productivity without large capital expenditures.

The new Kinetex XB-C18 provides a unique selectivity, incorporating two iso-butyl side chains at the base of the C18 ligand to reduce secondary interactions with residual silanols. These columns deliver enhanced separation and peak shape of basic compounds under neutral and acidic pH conditions. In comparison studies with other C18 columns, this new Kinetex phase has produced differences in peak elution order and improved separation of co-eluting compounds.

The new Kinetex C8 phase meets the United States Pharmacopeia (USP) specifications for Classification Code L7, enabling laboratories using L7 columns to realize the benefits of Kinetex core-shell technology while staying compliant with USP-allowable adjustments.

EPA-1613 and EPA-8290 Dioxin methods requires two GC columns, 5% phenyl and 225 GC columns (one for testing and one for confirmation) on two GC-HRMS instruments. The new Zebron ZB-Dixon exceeds EPA Dioxin method requirement by providing enhanced resolution for all Dioxin isomers using one GC column and single HRMS instrument.

Zebron ZB-Dioxin provides a single column Dioxin solution, reducing instrument down-time by 50%. This improves lab productivity, provides better sensitivity and offers greater resolution for the analysis of dioxins.

A systematic investigation was undertaken into the relative separation performance of five reversed-phase chromatography columns including some commercially new hybrid packed columns for a series of polycarboxylic acids and polyphenol compounds. Information theory (IT) and factor analysis (FA), together with a basic evaluation of retention information (band shape, retention factor and elution order) were used to compare four columns to a conventional C18 column. The results revealed very little difference in retention behaviour between the Phenomenex Aqua C18 column, the Waters XTerra RP C18 column, and the conventional Phenomenex Luna C18 column. However, there were notable differences in the retention processes between the Phenomenex Synergi polar-RP column, which is an ether-linked phenyl base with polar endcapping, and the Luna C18 column. The most significant differences were observed between the Luna C18 column and a Phenomenex Luna Cyano column. However, the limited degree of retention of the polycarboxylic acids and polyphenol compounds on the Luna Cyano column permits only limited use for the separation of these types of compounds. Overall, the Phenomenex Synergi polar-RP column exhibited the best performance for the separation of the test solutes compared to that of the conventional C18 column, with IT yielding an Informational Similarity of 0.99 and FA a moderate correlation coefficient of 0.70. The Phenomenex Synergi polar-RP column gave the best peak shape and offered substantial selectivity differences thereby providing a good alternative over the conventional C18 column for separating polycarboxylic acids and polyphenols. 2351a5e196
