Function and setup multi N/C 2100S
30
The reagent bottle must be positioned in the drip pan behind the right door. The
reagent bottle is labeled with a safety symbol and the name of the content and must be
filled by the user with 10% phosphoric acid.
The phosphoric acid is also required in the multi N/C 2100S pharma for initialization of
the analyzer. The acid is used for sample gas washing after combustion.
3.1.8 Extension options for the analyzer
The autosampler AS 60 is attached to the basic device using two Allen screws.
It is suitable for both homogeneous and inhomogeneous particulate samples. Each
sample can be stirred individually immediately before analysis. The stirring speed can be
selected. In NPOC mode the samples can be automatically acidified and purged. The
standard sample rack comes with 60 positions for 8 ml Vials. If limited sample volume is
available a 112 pos. rack with 1.8 ml HPLC snap cap vials can be utilized. Automatic
sample acidification is not available with this rack.
For TN
b
detection a chemiluminescence detector (CLD) can be connected to the analyzer
multi N/C 2100S (see section "Chemiluminescence detector CLD" p. 27).
The extension of the analyzer N/C 2100S with the external solids module HT 1300
enables the catalyst-free digestion of solid samples in a ceramic combustion tube. At
temperatures up to 1300 °C the ceramic boats can hold big sample quantities (up to 3 g)
in order to account for more inhomogeneous samples.
The combustion system of the multi N/C 2100S can be extended by a special reactor
and lock with manual feed for the analysis of small quantities of solid samples. Digestion
temperatures of up to 950 °C are achieved. The digestion is supported by catalysts.
The TIC in solid samples can be determined by extending the multi N/C 2100S with the
TIC solids module. Big sample quantities can be weighed into Erlenmeyer flasks.
Samples are digested by acid while stirred on a heating plate in order to release CO
2
from carbonates and bicarbonates.
The Analytik Jena AG does not offer solids modules for the multi N/C 2100S pharma.
