Sulfur analysis
Thread Content
Dear seniors: Regarding the analysis of sulfur in ethylene gas, which domestic laboratory is currently capable of achieving a total sulfur accuracy of 1 ppb? Which analytical instrument to use? Thank you!
Ultraviolet fluorescence sulfur detection can achieve precision of 1 ppb, and instruments for this purpose are available both domestically and internationally.
Using atomic absorption spectroscopy, the detection limit of flame atomic absorption method can reach the ppb level, while that of graphite furnace atomic absorption method can reach 10-10-10-14 g.
Gas Chromatography---Shimadzu 2014c with PFPD detector
Sulfur is generally analyzed using a flame photometric detector (FPD), and a PFPD can also be used to detect trace sulfides at the ng/g level.
TELDYNE UV fluorescence total sulfur analysis can also
Haichuan Haiyou is really generous, thank you!
The precision of 1ppb mentioned by the poster? Is it still 1 ppb?
Can atomic absorption spectroscopy actually be used to analyze sulfur? ? ? ? ? ? ? ? ? Sure enough, there are experts out there
Sulfur content at the PPb level may require an SCD detector; neither fluorescence nor Coulomb methods have such high sensitivity
