10 NANOCOLOR ® TIC-Ex V 1.0 / 05.15
1. Introduction
The NANOCOLOR
®
TIC-Ex is required during the sample preparation of MACHEREY-NAGEL
TOC tube tests. For evaluation of the total organic carbon (TOC) prior to determination the
inorganic carbon needs to be removed from the sample. The removal is accomplished by
purging of air with help of NANOCOLOR ® TIC-Ex through the prepared sample solution.
2. Technical data
Required power supply: external mains adapter: Input 100–240V, Output 9 V ,
1.5 A
Dimensions: 350 x 300 x 235 mm
Weight: 4.95 kg (without power supply)
Operating environment: 5–40 °C at 20–80 % relative humidity
3. Setup and commissioning
3.1 Working principle
The acidified sample solutions are put into the cuvette holder and placed in the premarked
positions of the NANOCOLOR
®
TIC-Ex. The preinstalled pipette tips are dipped into the
sample solutions by pressing down the lowering mechanism of the NANOCOLOR ® TIC-Ex.
After switching on the device, air is pumped through the sample solutions in the cuvettes for
five minutes. Hereby the inorganic carbon is removed as carbon dioxide quantitatively. After
elapsed time the process stops automatically. The pipette tips are removed from the solu-
tions and can be disposed using the removing mechanism on top. Afterwards the sample
solutions are treated following the next steps of the respective TOC test kit.
