MSTD258/TMD253H(Multi Thermal Desorption System Manual type)
Features
It is measureement system for out gassing from materials.
Sample (solid sample) is put into the heatr oven of MSTD258M Manual type. press START button swich, then it
goes automatically to heat sample , trap outgas from the sample. After the sampling , remove the sampe tube and
attach it to a thetmal desorption system TMD-253H or another to measure the tube. |

[outline]
- MSTD is an measurement system for out gassing of interior materiaks, construction materials, cleanroom materials, semiconductor materials, foos vessels, or multiple materials which can be a source of indoor air contamination.
- It is to measure a sample put into a chamber in an oven for heating |
| |
Builing materials out gassing gas screening measurement in indoor air chemicals
(Heating acceleration test)
- Test method of heating materials and outgassing measurement at an acceleerating rate.
- It is used for Comparison or Selecton of outgassing diffusion of builing materials
- It can be used for micro chamber than some L capacity.

[ Contaimination from human ]
Dried the 6mm ID Pyrex tube with ultra bath.
Measureed with MSTD-258
Check if blank peaks were not appeared.
Touch the Pyrex tube by hand.
Measure it again with MSTD-258
Fatty acid was detected, it should be come from human skin and squalene were detected very much.
DOP was detected as your concern.
Measure of the Pyrex tube touched by human.
