Essentia LC-15C

Characteristics of equipment components:

• LC-15C liquid delivery unit
  The LC-15C inherits the performance of Prominence LC-20AT, and through improvements in the transmission system, it exhibits excellent liquid delivery performance. The use of a floating plunger support mechanism improves the service life of the plunger and plunger sealing ring, making it a high-performance liquid delivery unit with excellent durability.
  
  
• SPD-15C UV Visible Dual Wavelength Detector
  SPD-15C is a UV visible dual wavelength detector that pursues performance and functionality. Its high sensitivity and wide linear range are derived from Prominence
  The excellent performance inherited from SPD-20A. Four measurement methods (dual wavelength detection, proportional chromatography, wavelength time program, and pump stop scan) can correspond to various measurement needs. Using optional solvent circulation valves can not only reduce analysis costs, but also be more environmentally friendly.
  
  
• SIL-10AF automatic sampler
  SIL-10AF is an automatic sampler that pursues reliability and high performance. Improved the quality of each component to ensure long-term stability for continuous use. *The injection method can achieve excellent quantitative reproducibility. Intelligent operations such as dilution, addition, and programming can be implemented, as well as pre-processing functions such as automatic sample derivatization.
  
  
• CTO-15C Column Temperature Box/Liquid Storage Box
  The CTO-15C has been redesigned to integrate a column temperature box and a liquid storage box, making it simple and practical. The liquid storage box can hold 3 mobile phase bottles with a capacity of 1000mL or 4 bottles with a capacity of 500mL; The column temperature box adopts a modular heating mechanism, which can accurately adjust the column temperature of the chromatography column and maintain the stability of analysis. At the same time, the manual sampler can also be installed on the liquid storage box to optimize the flow path volume of the system.
