Conclusions
Experimental data were critically
analyzed, and the results from both
methods were compatible and had
a linear correlation. The filter test
involves the potential of hazardous
solvent exposure for the lab technician.
It is a time-consuming process, as it
needs the preparation of every sample
to carry out the test. In contrast, the
ultra-centrifuge does not require
any hazardous solvent, and multiple
samples can be tested at a time.
The hazards associated with
handling kerosene and petroleum
ether are:
Petroleum ethers are extremely
volatile, have very low flash points,
and present a significant fire hazard.
Exposure to petroleum ether occurs
most commonly through inhalation
or skin contact.
e inhalation of kerosene fumes
might cause dizziness or nausea.
e mentioned solvents used in
the filter test are consumable. ere-
fore, it is recommended to adopt the
ultra-centrifuge for measuring insol-
uble contaminants for all samples, as
this method is safer and faster than
the filter test.
