IDEX Catalogue update 2024

Tags: , , , , , , , |

As the Global Premium Distributor for IDEX, Biotech Fluidics can present an updated IDEX catalogue with flow components, separation tools, and fluid management products. The catalogue has been thoroughly updated and corrected, and all obsolete items have been highlighted or removed. Nevertheless, it is still filled with plenty of fittings, connectors, valves, column hardware, and tubing for construction and maintenance of high precision fluidic systems. As always, Biotech Fluidics is ready to assist you and answer questions about what items would be most suitable for your current fluidics project. Learn more

Mobile phase inlet filter selection

Tags: , |

Eluent inlet filters prevents dust and other foreign particulate matters from entering the flow path of your liquid chromatography instrument. Such particles would otherwise eventually reach the column inlet, increase the system backpressure and might then also introduce radial flow heterogeneity which could affect peak shape. Biotech Fluidics offers a range of competently designed inlet filters in different materials and porosities for a variety of solvents and requirements. All of these have a defined homogenous pore size to effectively block particles above a certain size, while letting the mobile phase through without significant pressure increase. The Bottom-of-the-Bottle™ design of

Effect of tubing on peak efficiency for core-shell HPLC columns

Tags: , , , |

Selecting the appropriate tubing inner diameter (ID) when connecting a HPLC column can be crucial to maintain high peak efficiency while not achieving too high pressure. This is especially important when the efficiency is high and the total volume is small, as is the case with core-shell columns having narrow column inner diameter and shorter lengths. The data below highlights a study of how the average peak efficiency (i.e., N, number of theoretical plates) was influenced when the tubing ID was varied between the HPLC column and the UV detector flow cell during a study at the laboratories of

Order the new Chromanik-Biotech Application Dictionary on USB stick or download it as pdf file. This booklet contains over 120 application examples of how Chromanik HPLC and UHPLC columns solve separation and analysis problem and is the perfect tool to use for marketing and sales. Every example contains all the info to set up the separation, including mobile phase, flow rate, temperature and detection type. Most applications also come with chemical structural formula, making it easy for your customers to recognize molecules similar to their own. Witness the true power of Chromanik HPLC and UHPLC columns. With a wide

Micro and Nano LC-MS columns

Tags: , |

ChromaNik have released a range of Micro and Nano LC-MS columns with diameters from 0.5 mm down to 75 µm in different lengths. The columns are available with the SunShell high-performance core-shell materials in different particle sizes and with either C18 or Phenyl stationary phase chemistries. You can also choose the high-throughput material SunShell C8-30HT which has an exceptionally thin shell structure for extra fast separations, or the more traditional fully porous Sunniest material with C18 modification, or the SunShell C4-100 wide pore core-shell particles for separation of large molecules like monoclonal antibodies. The ChromaNik Micro and Nano columns

New biocompatible PEEK-lined stainless steel column hardware

Tags: , |

IDEX Health & Science introduces a new PEEK-Lined Stainless Steel (PLS) column hardware for biocompatible applications. The PLS column hardware combines the strength of our stainless steel UHPLC column (IsoBar) with the chemical inertness of PEEK polymer to ensure the integrity of biological samples by minimizing unwanted surface interactions while also allowing operation under harsh solvent or pH conditions. This hardware has been designed for demanding applications within the UHPLC realm. The PLS columns are available in a variety of standard lengths to accommodate various application requirements. Each column hardware design contains removable frits in Titanium or PEEK. For
