Compromised performance ??? . . . but Yet to be Determined in-house by US & Guaranteed !

Expected Mods . . . yet to be made by US > & to BE Optimized >Announced ! as compromise to avoid High(er) and extreme cost of UHPLC systems

  • VICI Or Rheodyne 0.5ul Manual Internal “Loop” Sample Size
  • Short Low(er) DeadVolume Transfer Lines In / OUT <20cm x0.13mm ID PEEK-CladSil
  • Standard UV Cell 10ul ( ???)  1oul UV Cell TOO Large ???  somewhat compromised > on fast “early” Peaks ?
  • We are sourcing Detector UV Cell OEM Tick 2ul UV Cell to be sourced! > semi-micro 2ul cell preferred
    For low Cost (China) HPLC
    Specs : ( for 3.5mm Chromanik SUNSHELL (Coreshell)

> 2.0ul UV MAX required > anticipated for better “Column Efficiency” ?

  • A Standard A/D Data System ( + S’ware)  should be quite adequate for the 1 to 5 secs peaks expected ! from the CoreShell Columns ( 2-5um   > 3.5u) )
  • at normal Pump Pressures <<6000psi

     
  • FORGET ULTRA-HPLC equipment at current exhorbitant COST from Your  usual  HPLC OEMs!
