    摘要： An interchangeable preconcentrator assembly comprises an outer housing and an inner housing defining a chamber. A biased urging member is held at least partially within the outer housing and slidably biased toward a surface of the inner housing. When the biased urging member is at least partially retracted, a space is defined between the urging member and the surface of the inner housing for accommodating at least one preconcentrator chip. A continuous fluid flow path is defined through the outer housing and through the space. The interchangeable preconcentrator assembly may further comprise at least one modular preconcentrator carriage.

    摘要： An analog-to-digital converter (ADC) is provided. The ADC includes a variable oscillator, a frequency divider, a clock circuit, and a counter. The variable oscillator is coupled to a sensor and configured to generate an oscillating signal based on a measurement generated by the sensor. The frequency divider is coupled to the variable oscillator and configured to divide a frequency of the oscillating signal. The clock circuit is configured to generate a clock signal at a defined frequency. The counter is coupled to the frequency divider and to the clock and is configured to generate a bit stream representative of a first number of periods of the clock signal during a second number of periods of the divided oscillating signal.
