Accurate mass measurement for the determination of elemental formula--a tutorial

The application of accurate mass measurement for the determination of elemental formula has its origin in the 1950s and for many years was only carried out using magnetic sector mass spectrometers. The availability of such measurements was limited due to the cost and complexity of the instrumentation and the need for considerable expertise to acquire and interpret the spectra. In recent years the incredible pace of instrumental development has changed this, particularly with the renaissance of time of flight mass spectrometry. This has resulted in instrumentation capable of making accurate mass measurements in a robust fashion becoming available to most practitioners of (mass spectrometry) MS, without some of the earlier technical challenges and at lower cost. In this review the variety of accurate mass measurement instrumentation and techniques and their relative capabilities are discussed, along with a range of applications requiring the determination of elemental formula.

Model-based measurement in physiology and clinical medicine

This paper outlines the scope and importance of model-based measurement in physiology and clinical medicine. The nature of model-based measurement is discussed, describing the basic methods for modelling and the criteria to be adopted when choosing models for use in clinical measurement. Having reviewed the underlying principles and approaches, the authors present two case studies. The first illustrates the potential role of model-based measurement in on-line instrumentation schemes for controlling the level of blood glucose in the diabetic patient. In contrast, the second case study illustrates the role of model-based measurement, implemented in an off-line computer scheme, in the management of patients suffering from a form of thyroid disease.     

Some fast mono multi-processor configurations for a single multi-parameter multichannel analyzer

Some single, multi-parameter multichannel analyzer configurations are reported. The analyzer is especially suitable for time and/or pulse-height spectra measurements from high counting rate sources. The various analyzer configurations arise from the need to reach a compromise between measurement requirements and analyzer speed and cost. The main element of each configuration is the Analog Devices 21060, a fast and flexible digital signal processor (DSP). The DSP takes part in the control of data acquisition, and updates spectra in real time without taking Host computing and Input/Output resources, so shortening the dead time of the whole spectrometric system. The instrumentation peculiar characteristics are as follows: (1) the true acquisition phase is an autonomous one; (2) the maximum count capacity is equal to 2³²−1 counts/channel; (3) the conversion gain is programmable. The maximum achievable value is 2¹⁰⁰; (4) spectra may be transferred from the instrumentation to the Host computer either at the measurement end or in the course of the measurement to display data during the accumulation process; (5) the maximum acquisition rate depends on the configuration. The monoprocessor configuration is able to acquire data and to update spectra without interruption at 10 MHz rate. Multi-bus configuration is recommended in the case that high conversion gain and/or fast multichannel structures are dealt with. Multi-bus configuration is needed if the spectrum must be transferred to the Host in the course of the measurement without interrupting the acquisition. (6) The instrumentation makes use of commercially available components. Their high integration and speed have led to powerful, compact, flexible, and modular instrumentation.
