Beschreibung
Zusammenfassung:	Embodiments of the present disclosure generally relate to apparatus and methods for verification and re-use of process fluids. The apparatus generally includes a tool for performing lithography, and a recirculation path coupled to the tool. The recirculation path generally includes a collection unit coupled at first end to a first end of the tool, and a probe coupled at a first end to a second end of the collection unit, the probe for determining one or more characteristics of a fluid flowing from the tool. The recirculation path of the apparatus further generally includes a purification unit coupled at a first end to a third end of the collection unit, the purification unit further coupled at a second end to a second end of the probe, the purification unit for changing a characteristic of the fluid.
