1) While the CS-r uses a horizontal furnace, the CS-580A is equipped with a vertical furnace in order to integrate the automatic sample changer “Autoloader”.

2)While the CHS-r uses a horizontal furnace, the CHS-580A is equipped with a vertical furnace in order to integrate the automatic sample changer “Autoloader”.

3) Compared to the CW-800 the CW-800M can process different carrier gases (N2, O2) and change temperatures during measurement (ramping).
