vario MACROElemental 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

INTRODUCTION

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.

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 soil sample into smaller

size

Folded the tin capsule

using tweezers

STANDARD USED OF ELEMENTAL ANALYSIS

SULFANILAMIDEUREAL-CYTINEBIRTHBBOTNC SOILNCS SOILSOIL REFERENCE(RMS)

CHECKLIST BEFORE RUN THE SAMPLE!!!

Temperature : 950˚c, 850˚c & 800˚cMode : CNS mode @ stanbyPressure : 0.8-1.2 barFlow of He gas : 501 mL/minFlow of O2 gas : 10 mL/min80 samples in the autosamplerKey in the data in the table Ready to be run

How does it work???

Result!!!

Area of NCS SOIL = Absorbance of NCS SOIL 1599 = 0.181Area QC TG 1281 = 1281 x 0.181

1599 = 0.145 x 0.21 0.181 = 0.168 N% of QC TG

CALCULATIONS :

CONCLUSION :

• ADVANTAGES : -Zero waste -Rapid process -No chemical usage -Environment free -Decrease the uncertainty

• DISADVANTAGE : -Leaking of gas
