CHNS-O Analysis

Analyte

organic and inorganic substances in solid and liquid samples

• Sample size: 2 mg normally, 0.1 - 300 mg (depending on the nature of the sample)

Equipment

FlashEA 1112 CHNS/O Automatic Elemental Analyzer from Thermo Scientific with 2 Autosampler MAS200R

Evaluation methods and targets

quantitative determination of percentages of carbon, hydrogen, nitrogen and sulfur as well as oxygen

• Measuring range 0.01 - 100 %
• Accuracy:

  Theoretical values	Experimental values
  100 ppm	100ppm ± 10ppm
  0.10 %	0.10 % ± 0.01
  1.00 %	1.00 % ± 0.02
  10.00 %	10.00 % ± 0.1
  50.00 %	50.00 % ± 0.3
  90.00 %	90.00 % ± 0.3
