Elemental/CHNS analyser

Photo of CHNS
  • Elementar vario EL cube
  • Determines the percentage of carbon (C), hydrogen (H), nitrogen (N), and sulfur (S) elements in a solid or liquid sample
  • Requires minimal sample preparation
  • Provides micro-analysis of samples in the lower microgram range with no compromise
  • Semi-macro analysis for CHNS in up to 1 g soil
  • Equipped with two detectors: a Thermal Conductivity Detector (TCD) and a Non-Dispersive Infrared Detector (NDIR).
 

X-ray diffractometer (XRD)

XRD

  • PANanalytical Empyrean II
  • Analysis of powders, thin films, nanomaterials, slurries and solids
  • Performs mineral identification and quantification
  • Maximum usable range (depending on accessories) -111°< 2θ <168°; 2θ linearity equal or better than ±0.01°
  • Fully ceramic X-ray tubes manufactured by PANalytical under cleanroom conditions; designed for 60 kV operation, allowing optimal performance for Mo and Ag sources
