How to calculate Sulphur contents

[zamu2010]

Dear folks,
I want to calculate sulphur contents in a Bio-mass product.
From my process simulation, I can see how much sulfuric acid is going there.
Can I calculate the sulphur contents from this or should I send the sample to a lab???
Thanks in advance for your advice on the subject.
