3. vario MACRO
Elemental Analyzer
•Elemental Analyzer is a combustion technique that determines weight percent
carbon, hydrogen, nitrogen, sulfur or oxygen in a variety of sample types
•Capable of operating in 3 modes; CHN, CHNS and Oxygen

4. vario MACRO
Elemental Analyzer
•CHNOS elemental analyzers are essential in
determination of carbon, hydrogen, nitrogen
and sulfur in organic matrices and other
types of materials.
•CHNS analysis can also determine the N
source, total organic and CN ratio.

8. SAMPLE PREPARATION OF SOIL SAMPLE
Weighed 60
mg of soil
sample Covered the
top of the
sample with
Tungsten
Transferred
the sample
into the tray
Shaped the

Folded the
tin capsule
using
tweezers

10. Temperature : 950˚c, 850˚c & 800˚c
Mode : CNS mode @ stanby
Pressure : 0.8-1.2 bar
Flow of He gas : 501 mL/min
Flow of O2 gas : 10 mL/min
80 samples in the autosampler
Key in the data in the table
Ready to be run

11. How does it work???

13. Area of NCS SOIL = Absorbance of NCS SOIL
1599 = 0.181
Area QC TG 1281 = 1281 x 0.181
1599
= 0.145 x 0.21
0.181
= 0.168 N% of QC TG

14. CONCLUSION :
• ADVANTAGES :
-Zero waste
-Rapid process
-No chemical usage
-Environment free
-Decrease the uncertainty
• DISADVANTAGE :
-Leaking of gas
