Laboratory Instrumentation

Simplified instrumentation for the clinical laboratory.

The advances that have taken place so far in the short history of clinical chemistry have unfolded almost entirely in countries with highly developed technologies and economies. And it would appear that there has been an accelerating tendency toward increased sophistication and escalating costs. Until 1974, for example, in the Division of Clinical Chemistry at the Clinical Research Center in Lo...

Weathering : Laboratory Analyses and in - Situ Instrumentation

Instrumentation for Laboratory Exercises in Basic Electrophysiology *

The apparatus described below was used during the past year to provide first-year medical and graduate students with an opportunity to observe and study for themselves basic phenomena characteristic of the excitable tissues in general and nerve in particular. The apparatus represents the culmination of numerous attempts on our part to design and develop an arrangement that would be relatively s...

Teaching Communication Protocols Used In Instrumentation Laboratory

We present a system for teaching different serial communication protocols used in instrumentation laboratory. The system is implemented using XESS prototyping boards (XSBoards) each one equipped with either a Xilinx FPGA or CPLD and an 8031 microcontroller (μC)[1] and several intelligent sensor types. The system was used for implementing and testing the IC, SPI, 1-Wire and other company specifi...

An aid to interfacing analytical instrumentation to laboratory computer systems

Most current laboratory computer systems are based on operating systems designed for multi-terminal access to a shared data-base, and not for real-time data acqusition from on-line analytical instruments. Several years ago this would have caused severe problems, because most instruments produced data output in the form of a varying analogue voltage which needed to be sampled, digitized, and mon...
