HPLC PROGRAMME: The new KONIK HPLC 580

 The GIBNIK technical team has been developing HPLC’s since 1985. The New KONIK 580 HPLC is GIBNIK’s answer to todays and future needs. Its tower design and small foot print of 30x50 cm takes little bench space. Its robustness, flexibility and reliability are second to none, converting the HPLC 580 in a laboratory workhorse. GIBNIK is continuously improving its HPLC programme. Since the introduction of the KONIK HPLC 500 launched in Chemasia 1985 in Singapore, 4 generations of HPLCs have paved the road to this 5th generation where GIBNIK has synthesised all its know how and experience over the years.Download Catalog

While model 600 is being redesigned to 600 B Plus for optimal HPLC+GC-MS, the KONIK 580 HPLC has been purposely updated for fast/high pressure HPLC , in both low pressure 4 solvents gradient formation, or high pressure binary gradients. An upper pressure limit of 60 MPa (600 barr or 8.700 psi), and flow range from 0,01 to 10 ml makes the 580 HPLC suitable for micro and conventional HPLC and a wide range of columns particle sizes (1,5, 3, 5 and 10 microns) including new low backpressure hollow packings . Isocratic, and preparative versions (40 Mpa and 0,1 to 50 ml/min) of the 580 pump are also available by easy exchange of the pump head. The 580 design has facilitated improvements on the pump flow control with even lower pulsation than previous models, better accuracy and reproducibility of gradient formation, and a more compact oven for better column temperature control. The 580 oven is now housed in the same modular chassis of the 580 series. 

The 580 HPLC offers again, like in the previous model 500, four solvent, low pressure mixing gradient formation for utmost flexibility and reproducibility with built in solvent degassing. Column and detector switching, as well as column back flushing are interesting options to increase productivity. The HPLC 580 has been purposely designed for utmost compatibility for Multidimensional HPLC+GC, HPLC+GC-MS and/or HPLC-MS, hence facilitating future expansions while opening new dimensions for critical analysis.

As a direct advantage of the intrinsic modularity of the GIBNIK product programme all options in the KONIK 580 can be fitted at any time in the future. This facilitates coping flexibly with future analytical needs.

 

 

 

The KONIK 580 PUMP

The 580 pump is a multipurpose, multifunctional pump available with three pump heads optimised for:

  • Analytical HPLC with flow range from 0,01 to 10 ml and
  • Semi preparative, with flow range up to 50 ml and
  • Preparative HPLC with flow ranges from 1 to 100 cc/min upon exchange of pump head.

Can work as

  • Isocratic
  • Four solvents gradient with low pressure mixing concept, and/or
  • High pressure binary gradient formation.

With flow rate ranging from 0.01 to 10.00 ml/min. and a pressure limit of 40 MPa (400 Bar/5.800psi) this pump is suited for most analytical applications in liquid chromatography. It is designed following the KONIK HPLC 500 Isokinetic Flow Delivery principle we pioneered in 1985. This implies the use of dual pistons working in series to minimize pulsation with an improved pulsation dampening algorithm, while improving solvent mixing in the gradient forming process.

The KONIK 580 Pump facilitates highly reproducible and accurate gradient forming by mixing at low pressure the chosen solvents prior to introducing the mixture in the pump head. This is done by the use of very fast, microelectrosolenoid valves under computer control. User selects the solvents and defines the desired gradient and built in algorithm does the rest (see the KONIK 580 Solvent Manager).

cataleg-HPLC 580-06-3



The 580 pump can also be used in isocratic runs by choosing any of the 4 solvents and or producing constant mix of any of the four in any chosen proportions. Mechanically the pump offers utmost reliability and robustness, along with accurate and reproducible flows. Easy exchange of pistons, seals and check.

When using certain chemically aggressive mobile phases, such as buffered solutions, it is important to be able to rinse, wash and/or flush pistons and seals to properly protect them. A piston/seal backwash option is offered for the KONIK 580HPLC Pump.

The KONIK 580 SOLVENT MANAGER

This module is used with the KONIK 580 Pump for gradient formation of up to 4 solvents mixed at low pressure. It is made up of four way microsolenoid valves controlled by the KONIK 580 Pump. The 580 SOLVENT MANAGER includes a highly effective, fast response and low internal volume, 4 channel solvent degasser with advanced gas permeation membrane technology. Solvent degassing is important to prevent bubble formation upon low pressure solvent mixing and it is much more economical than He degassing as we used in older model 500. The Solvent Manager tray fits up to 6 solvent bottles. An additional solvent selection valve can be optionally fitted.

Accurate gradient formation is a very important feature when the HPLC is coupled to the GC for Multidimensional HPLC+GC or HPLC+GC-MS. In fact the HPLC fraction or fractions are introduced into the patented HPLC+GC interface by switching a valve located at the column outlet. This is done on a time bases in relation to retention volumes of the particular method and gradient chosen. Accuracy and reproducibility of the gradient formed is key to integrity of the fraction(s) introduced and hence reproducibility and reliability of results.
