Spot tests

From: Lydia C. Egunnike <l.egunnike>

Does anyone know of a safe, simple technique (such as a spot
test) for detection of sulphur in paper-based material?  I was also
wondering if a safe way of spot testing for lignin had been found to
replace the aniline sulphate and phloroglucinol tests ?
