Peptide mapping and separation of low molecular weight proteins using a mobile phase.

Peptide mapping and separation of low molecular weight proteins using a mobile phase.

Peptide mapping using formic acid allows for more sensitive detection with ESI-MS.

Peptide mapping using formic acid instead of TFA enables more sensitive detection with ESI-MS. The CSH130 C18 shows outstanding performance regardless of the acidic modifier used, making it ideal for LC/MS-based peptide mapping. In LC/MS analysis using a formic acid mobile phase for enolase tryptic digest, the CSH130 C18, 1.7μm column achieved a 30% higher peak capacity compared to common fully porous or superficially porous C18 columns of the same particle size. Furthermore, analysis results of high molecular weight peptides and low molecular weight proteins demonstrated that the CSH130 C18 column with a pore size of 130Å is suitable for the separation of polypeptides up to approximately 10 kDa in molecular weight. 【Application Benefits】 - High peak capacity and unique selectivity compared to other C18 columns - Compatibility with formic acid and ESI-MS - High separation ability for analytes up to approximately 10 kDa - CSH130 C18 has been QC tested with cytochrome c tryptic digest For more details, please contact us or download the catalog.

T054 NFC Key Management System for Banks and Security Companies

T054 NFC Key Management System for Banks and Security Companies

Utilize NFC tags with opening detection features for managing keys at banks and security companies to prevent unauthorized access!

Recently, there was news about valuables being stolen from bank safety deposit boxes using spare keys. It is possible to prevent such incidents by attaching an NFC tag with an opening detection feature to the envelope! What is an NFC tag with an opening detection feature? It is a special label that has an opening detection function added to an NFC tag that can be read simply by touching it with a smartphone. When the label is torn and touched with a smartphone, it changes from "unopened" to "opened." This prevents the outflow of keys placed in an opened key and helps prevent unauthorized opening of the envelope! By using it in conjunction with an NFC item management system, it is also possible to manage the borrowing and returning of keys! 【Features of the NFC Item Management System】 1. Simple operation with just a touch You can register lending, returning, and moving by simply touching the NFC tag with your smartphone. 2. Real-time management and tracking Data is centrally managed in the cloud. The location, usage history, and users of items can be tracked in real-time! 3. Strong traceability Records are kept of "when," "where," and "what was used," allowing for identification of causes and clarification of responsibilities in the event of a problem!

ZORBAX Rx Reverse Phase HPLC Column

ZORBAX Rx Reverse Phase HPLC Column

Rx-C18 is recommended for separation in low pH regions! It shows excellent stability and peak shape.

The "ZORBAX Rx Reverse Phase HPLC Column" is suitable for high-throughput analysis. It shows different selectivity compared to Eclipse XDB-C18 and StableBond SB-C18 in the low pH range, and StableBond is recommended for high-temperature applications. Additionally, Rx-C18 is manufactured using dimethyl octadecyl silane and demonstrates excellent stability up to pH 9 due to the lack of end-capping. 【Features】 ■ Shows different selectivity compared to Eclipse XDB-C18 and StableBond SB-C18 in the low pH range ■ Exhibits excellent stability and peak shape in low pH applications ■ Rx-C18 is manufactured using dimethyl octadecyl silane and demonstrates excellent stability up to pH 9 due to the lack of end-capping ■ Rx-C8 is the same product as SB-C8 *For more details, please refer to the PDF document or feel free to contact us.

ZORBAX Extend-C18

ZORBAX Extend-C18

Improvement of retention, separation ability, and peak shape in base compounds! Introducing ZORBAX reverse phase HPLC columns.

The "ZORBAX Extend-C18" utilizes a groundbreaking bidentate C18-C18 bonding technology, enabling the development of high-separation methods in high pH regions while being a silica-based column. The unique bidentate bonding and double-end capping enhance stability at high pH. It improves retention, separation capability, and peak shape for basic compounds. To extend column life, it is preferable to use triethylamine, ammonium hydroxide, or pyrrolidine as buffer solutions, while phosphate buffers are not recommended. 【Features】 - High separation efficiency and long lifespan in high pH regions (up to pH 11.5) - Improved stability at high pH due to unique bidentate bonding and double-end capping - Higher efficiency and superior peak shape compared to polymer-based columns - High sensitivity and separation for LC/MS analysis of peptides and proteins *For more details, please refer to the PDF document or feel free to contact us.
