Introduction

The upgraded Varian ProStar 325 LC detector delivers:

  • Superb sensitivity
  • Low noise
  • Wide wavelength range of 190 nm to 900 nm
  • Information rich detection with the optional dual wavelength ratio capability
  • Provides the widest dynamic with dual path length flowcell range from 50 mAu up to 70 Au
  • Easy scale-up from microbore to preparative LC applications with a single detector

And with Varian's philosophy of continual improvement, the ProStar 325 has got better!
