Product details:
Analysis method:
- high temperature combustion or pyrolysis of the sample and conversion of the elements into gaseous products
- separation of the analysis gases by temperature programmed desorption (TPD) and
- detection at a TCD (IR optional)
Operating modes:
CHNS, CHN, CNS, CN, N, S as standard with TCD
S with IR detection optional
O with TCD or IR detection optional
Cl with photometric detection optional
Digestion temperatures: adjustable up to 1200°C, for special applications also selectable up to 1400°C
(by combustion of the tin vessels a temperature of approx. 1800°C is temporarily
reached)
Detection range:
C: 0-7 mg (or 100%) O: 0-2 mg
N: 0-2 mg (or 100%) Cl: 0-2 mg
H: 0-1 mg (or 100%)
S: 0-2 mg (or 100%)
Detection limit:
< 100 ppm with TCD
2 ppm with IR detection for S
Standard deviation: < 0.1% abs. (1-2 mg sulfanic acid)
Calibration: Multi point calibration, regression linear to the 4th order, stable
over months
Sample weight: 0.02 - 10 mg organic substance or up to 1 g soil sample
Analysis time: self-optimizing depending on element content and sample weight
e.g. CHNS 10 min
CHN 8 min
CN 6 min
N 3 min
Autosampler: 120 positions in a magazine as standard, reloadable any time during operation
Gases:
He: 99.995% purity 3 l/analysis
O2: 99.995% purity 0.05 l/analysis
Instrument control:
Operation and control via PC under Windows®;
All instrument functions are digitally controllable, the comprehensive operation
software includes e.g. automatic leak test, extensive error diagnosis,
monitoring of the maintenance cycles, sleep-/wake up function, statistical
evaluation and almost unlimited memory capacity for analysis data incl.
graphics.
Integration in data networks like LIMS and the possibility of remote control
and diagnosis via the internet.
In full compliance with 21 CFR Part 11 (option).
