SPECTROSCOPY
quality assurance of pharmaceutical formulations.
IMPROVING SNR High Speed Averaging Mode is a hardware- accelerated signal averaging function accessible via the OceanDirect device driver that improves SNR performance in Ocean Insight spectrometers. With better SNR comes higher quality spectra and more accurate results.
SNR is a function of several factors,
some more easily managed than others. For example, signal averaging to improve SNR can be carried out in operating software on the host computer but can take longer to process than what may be acceptable for your application. HSAM overcomes that limitation by enabling many more spectral averages over a given time period, yielding a much higher SNR per unit time. Tis can be important for time-critical or real-time applications, where decisions must be made very quickly and with high accuracy. Te advantage of HSAM can be quantified
easily. For example, the standard operating software can process 10,000 averages in about two seconds. But because HSAM performs the averages on the hardware, the

OceanDirect device driver can process 10,000 averages in 200ms – 10x faster.
SUMMARY From determining concentration levels of proteins to identifying contaminants in pharmaceutical materials, the Ocean HR2 spectrometer delivers research-grade spectrometer performance in an
instrument that works equally well in the lab or on the line, as part of a standalone setup, or as a key subsystem or component within another device.
