Technical specifications

LC detector and system supplies
  • LC Columns: 
    Restek's column lines (Raptor, Force, Roc) are designed for high performance and durability in HPLC and UHPLC applications. 
     
    • They are made with different particle types and frit sizes to optimize efficiency and pressure stability. 
       
    • Materials are 316 stainless steel, and end fittings are compatible with many common brands like Valco, Parker, Upchurch, and Swagelok. 
       
  • Fittings:
    • EXP® Reusable Fittings: These are hand-tightened fittings that provide a high-pressure seal without tools. 
       
    • Stainless Steel Fittings: A good choice for high-pressure applications, requiring wrenches for installation. 
       
  • Detector Lamps: 
    Restek offers long-life deuterium lamps for various Waters detectors, such as those for the ACQUITY PDA/TUV 2489/2998 and 996/2996 models. 
     
  • Leak Detector: 
    A handheld electronic leak detector that identifies a broad range of gases and provides an audible tone and LED display to indicate the severity of the leak. 
     
How to use and maintain
  • Column Installation: 
    When installing a new column, carefully reset the nut and ferrule on the fittings to ensure proper seating before tightening, which can prevent issues with efficiency and removal. Always remove the PEEK end plugs before installation and consult the instrument's manual for specific instructions. 
     
  • Preventing Baseline Issues: 
    To avoid baseline errors from detector problems, perform routine maintenance. Using and degassing HPLC-grade solvents, flushing the column with a strong solvent at the end of the day, and maintaining the lamp are all recommended to prevent noise spikes and keep the detector cell clean.
