On-line monitoring is often used to observe a process to ensure quality on a constant basis. The MV-2000 Series UV-visible PDA spectrophotometer offers excellent performance for a variety of applications and is highly configurable for a wide range of sample analyses. With the ability to perform transmission or reflection measurements, the MV-2000 Series can be used to make in-situ or on-line measurements for applications such as the monitoring chemical reactions or physical vapor deposition, manufacturing and polishing processes, and film thickness measurement.
