LAR QUICKTOCultra – All Type of Rough Samples

LAR QuickTOCultra Analyser is the most reliable measurement system for the roughest waste water applications.

Due to high temperature combustion at 1200 deg C, this model is excellent in handling sample content, high salt, fatty and high particle samples.

Almost all type of sample can be measured accurately by this unit. Due to combustion at 1200 deg C, NO catalyst is needed.

LAR’s QuickTOCultra is the ultimate online TOC analyser for the determination of total carbon (TC), total organic carbon (TOC), total inorganic carbon (TIC) and dissolved organic carbon (DOC) even for the most difficult waste water applications.

  • Catalyst-free
  • Multi-stream measurements is possible, up to 6 streams
  • No filtration necessary
  • High salt concentrations Sample possible, up to 30% NaCl
  • No memory effects
