The following autosamplers are available for the analyzer:
AS vario with various tray sizes
¡
AS vario ER with various tray sizes and canula flushing
¡
AS 10e for 10 samples
¡
¡ AS 21hp for 21 samples
¡ EPA Sampler with piercing function
The addition of the external HT 1300 solids module to the analyzer enables the cata-
lyst-free digestion of solid samples at temperatures of up to 1300 °C in the ceramic com-
bustion furnace. The ceramic boats allow input of large sample sizes (up to 3000 mg).
This can compensate for sample inhomogeneities.
The TIC determination in solid samples can be performed by equipping the analyzer with
a TIC solids module. Large sample amounts can be weighed in an Erlenmeyer flask. The
sample is acidified and magnetically stirred on a heating plate to digest carbonates and
hydrogen carbonates to CO
No solids modules are available for the multi N/C pharma UV model.
The analyzer is a compact and powerful device for determining the total carbon content
in aqueous samples.
