Consumables and reagents for ultra-low mercury testing are screened by atomic fluorescence to ensure low mercury
backgrounds enabling the analyst to achieve the required 0.2ppt detection limit.
Concentrated Bromate/Bromide Solution
For low-level mercury determinations by atomic fluorescence, 10mL of concentrated reagent
is sealed in a Teflon tube. Just snip and dilute to 100mL in a volumetric flask. Ten tubes per package.
