What are the differences between PAT-Cell-Press and PAT-Cell-Gas?

	PAT-Cell-Press	PAT-Cell-Gas (P, S, SP)
Cell is dedicated to:	The quantitative (cumulative) measurement of the gas evolved / consumed during the electrochemical cycle by measurement of the gas pressure	Time resolved analysis of the gas evolved / consumed during the electrochemical cycle in combination with a mass spectrometer and controlled gas supply
Preferred operation mode:	Pressurized cell without gas flow	Flow-through with gas analysis at outlet and mass flow controller at the inlet
Plug flow:	not available	Almost perfect when using the lower plunger with flow field; significant back-mixing when using the lower plunger with perforated plate
Applicable to:	• Aprotic chemistries such as Li-ion, Li-air, super cap • Some aqueous chemistries may work, but compatibility must be checked by the user	• Aprotic chemistries such as Li-ion, Li-air, super cap • Some aqueous chemistries may work, but compatibility must be checked by the user
Upper electrode:	Any compatible electrode, either self-standing or with metal foil current collector; standard upper plunger or perforated upper plunger	Any compatible electrode; often Li metal or LFP are used here as a Li ion source; preferably there is no gas evolution or consumption at this electrode
Lower electrode:	Any compatible electrode, either self-standing or with metal foil current collector; standard lower plunger or perforated lower plunger	The lower electrode is seated on a plunger with flow field and must therefore be gas permeable, either self-standing or on current collector mesh. The gas evolution / consumption at the lower electrode is subject of the measurement.
