SecurityLINK HPLC/UHPLC Column Connectors

High efficiency and good peak shape are essential to minimize or eliminate dead-volume within any HPLC and UHPLC system. Fitting connections routinely made to the column inlet and outlet are a contributor to additional dead-volume leading to lower than expected efficiency, peak tailing, or misshaped peaks. SecurityLINK HPLC/UHPLC fittings with integrated or external torque limiting technology, provide a convenient solution that eliminates column over- and under tightening which could result in column damage and poor analytical results.

Better HPLC/UHPLC results with zero dead-volume connections
Torque limiting technology prevents over and under tightening
Pressure rated to 19,000 psi (1,310 bar)

Available in two formats:

About SecurityLINK Technology

The SecurityLINK LC connectors utilize torque-limiting technology that simplifies the system-to-column connection while ensuring proper seal and preventing column damage due to overtightening.

Whether you choose the standard connector with integrated torque limiting (SecurityLINK) or the small footprint connector with torque limiting tool assistance (SecurityLINK ET), you're assured of reliable performance and enhanced security for your LC applications.

The Dead-Volume Difference

SecurityLINK Connectors vs Conventional Fittings

Poorly connected fittings are often the causes of carryover, band broadening, and peak tailing. Standard SecurityLINK and SecurityLINK ET fittings offer zero dead-volume connections every time.

Conditions for both separations:

Column:
Luna™ Omega 1.6 µm C18

Dimension:
50 x 2.1 mm

Part No.:
00B-4742-AN

SecurityLINK Part No.:
AJ1-1421

Mobile Phase:
Water / Acetonitrile (35:65)

Flow Rate:
0.5 mL/min

Temperature:
25 °C

Injection Volume:
0.2 µL

UV @ 254 nm

Sample:
1. Uracil
2. Acetophenone
3. Toluene
4. Naphthalene

Superior Robustness and Reproducibility

Column Performance

While typical fittings are not cross-column compatible and prone to cause column damage with overtightening, SecurityLINK safely and easily allows you to continuously attach and detach columns. To illustrate the high robustness and durability of the SecurityLINK LC Fitting System, the fitting was disconnected and reconnected 100 times to a highly sensitive sub-2 μm core-shell UHPLC column.

Conditions for all columns:

Compatibility with Column Vendors

Consistent Results with SecurityLINK

SecurityLINK LC Fittings were designed to be compatible with the majority of LC columns and systems that are available on the market. That gives you the ability to utilize this easy to use fitting on each system and with multiple columns. To prove this, the SecurityLINK was evaluated below for compatibility with different column vendors; Phenomenex, Waters®, and Agilent®.
