Axiom Analytical Inc has announced its fibre-optic coupled FPT-830 Near-IR Transmission Probe. The new probe shares many of the characteristics of the Company’s well-established FPT-850 on-line process analytical probes, including the extreme robustness provided by the Company’s patented welded metal window sealing technique (1). However, the new fibre-optic probe also features reduced diameter (18 mm) and thus is tailored to providing optimum performance when used with the relatively small reaction vessels often employed during pharmaceutical process development and scale-up for on-line process control.
In common with the FPT-850, the FPT-830 employs a single pass through the sample gap. This provides two important advantages compared to double pass 'transflectance' probes. First, it eliminates the possibility of stray light offset caused by backscatter from either the sample or the probe windows. Second, it provides twice the window separation for a given optical pathlength, greatly enhancing sample flow between the windows.
The FPT-850 is widely used for on-line NIR and UV-Visible process analysis in the chemical and petroleum industries. Its ability to be mounted directly in a process line or vessel has brought true in-situ analysis to these industries, eliminating the need for costly and trouble-prone sample conditioning systems. The FPT-830 extends this capability to smaller process lines and reaction vessels. In addition, its reduced weight makes it ideal for many pharmaceutical development and other laboratory applications.

Multiplexer provides rapid switching between single UV spectrometer and multiple sampling probes
Axiom Analytical Inc has announced its FMX-200U Series Fibre-optic Multiplexers. The new multiplexers extend the capabilities of the Company’s FMX Series Multiplexers into the ultra-violet region of the spectrum, providing rapid switching between up to 16 sampling points. It is ideal for use in applications such as pharmaceutical dissolution monitoring and the analysis of aromatic compounds and other strongly absorbing chromophores.
The FMX-200U maintains the unique benefits of the FMX Series, including a very high degree of repeatability combined with an absence of the channel-to-channel frequency shifts characteristic of other multiplexer designs. This performance results from the use of a pair of proprietary retro-reflecting switching prisms to switch both the transmitted signal from the spectrometer and the signal returning to the optical detector. (US Patent 6,009,219)
FMX Series multiplexers can be controlled from a remote computer via a choice of RS-232, RS-422, or RS-485 ports. System commands are provided in two forms: a custom ASCII protocol, and a subset of the OPTO-22 instruction protocol. In addition, the multiplexers can be controlled by the Symbion Suite of analytical instrument software. This enables them to be integrated into comprehensive systems for both laboratory and on-line chemical process analysis.

Enhanced performance for laboratory and QC mid-infrared analysis
Axiom Analytical Inc has announced its DPR-230 sample compartment mounted attenuated total reflectance (ATR) probe for FTIR spectroscopy. The new probe is the successor to the popular DPR-210 which has found widespread use in applications ranging from chemical and pharmaceutical research to incoming inspection of raw materials. In common with its predecessor, the DPR-230 features broad mid-IR spectral response, providing detailed quantitative analysis based on specific chemical functional groups. It comes equipped with an interchangeable sample compartment mounting plate to mate to any specified FTIR spectrometer. In addition to the considerable capabilities of the DPR-210, the new probe features higher transmission and easier interchange of ATR elements.
The design of the DPR-230 allows it to pivot around the spectrometer’s sample beam axis so that it can be dipped into any sample container for rapid screening or detailed analysis. Cleaning is achieved by simply dipping the probe into a beaker of solvent and wiping it off with a soft tissue. Interface to laboratory reaction vessels is provided by a sliding tapered joint that can be locked in any position on the probe. With its high transmission (up to 20%, depending on spectrometer beam geometry), the DPR-230 provides highly sensitive chemical analysis when used with the DTGS infrared detectors, standard with most FTIR spectrometers.
The DPR-230 is the newest member of Axiom Analytical’s comprehensive family of products based on the Company’s patented ATR immersion probe technology*. Other members of the family include models for on-line process analysis as well as diamond ATR probes for the monitoring of highly aggressive chemical reactions.
