Integrated process spectrophotometer

September 2006 Analytical Instrumentation & Environmental Monitoring

Ametek's Western Research IPS-4 integrated process spectrophotometer is a new analyser that employs modern electronics and diode array technology to perform a wide variety of liquid and gas analysis using UV-VIS spectroscopy.

The IPS-4 is capable of detecting, quantifying, and compensating for multiple chemicals of interest and interfering species. Up to eight components of interest can be measured simultaneously through the combination of a modern, diode array-based optical system with Ametek's proprietary process-ready electronics.

This combination offers many advantages such as no moving parts, a high signal-to-noise ratio, minimised stray light effects, fast and full spectral acquisition, and a wide dynamic range.

The IPS-4 has a lamp life greater than two years, offers fast Ethernet and MODBUS communications, and is supplied in an enclosure that meets IP65 requirements.

Designed to increase reliability, the optical system reduces the need for routine maintenance, thereby drastically reducing the cost of ownership. There is no filter wheel or motor to maintain, no optical filters to replace and no optical couplings to align.

When installed outdoors, the IPS-4 will tolerate ambient temperatures from -20°C to 50°C without external heating/cooling. The analyser is 780 mm in width, and when installed indoors, occupies minimal wall space.

To meet the varied needs of customers, the IPS-4 is equipped with numerous analog and digital communications capabilities. A detailed, multiline display and a 22-key keypad provide the primary local indications. The analyser also communicates through a variety of analog signals, alarm contacts, and three types of digital communication.

Ametek is represented locally by OEN Enterprises.

Keeping an eye on invisible radiation
Omniflex Remote Monitoring Specialists Analytical Instrumentation & Environmental Monitoring
At its peak in 1994, the energy generation capacity of the UK’s nuclear power stations was 12,7 GW across 16 plants. In 2024, the capacity has fallen to around 5 GW, and the number of stations is down to nine. However, this is far from the end of the story as spent nuclear fuel remains radioactive for centuries, and requires rigorous safety processes to safeguard against leaks.
