Mass Analyzers: Common Types

725
The quadrupole mass analyzer consists of four cylindrical metal rods arranged in a diamond carrying a DC voltage and a radio-frequency AC voltage. The motion of ions through the quadrupole depends on the field strength, causing only ions of a certain m/z to resonate successfully and strike the detector at a given field strength. Though the transmission rate for these analyzers is high, the exact elemental composition of the sample is not determined because of low resolution; however, they are...

Mass Analyzers: Overview

841
The mass analyzer is a crucial component of the mass spectrometer. In the ionization chamber, the vaporized sample is bombarded with a high-energy electron beam to generate a radical cation and further fragment into neutral molecules, radicals, and cations. A series of negatively charged accelerator plates accelerate the cations into the mass analyzer. The mass analyzer separates ions according to their mass-to-charge (m/z) ratios and then directs them to the detector. The common types of mass...

Electronic Distance Measuring Instruments

129
Electronic Distance Measuring Instruments (EDMs) are essential tools in modern surveying, offering precise distance measurements by emitting electromagnetic signals and calculating the time required for these signals to travel to a target and return. Two primary types of signals are used in EDMs — light waves and microwaves — each suited to specific environmental and distance requirements. Light-wave-based EDMs utilize either infrared or laser light, providing high accuracy over...

Uncertainty in Measurement: Reading Instruments

47.2K
Counting is the type of measurement that is free from uncertainty, provided the number of objects being counted does not change during the process. Such measurements result in exact numbers. By counting the eggs in a carton, for instance, one can determine exactly how many eggs are there in the carton. Similarly, the numbers of defined quantities are also exact. For example, 1 foot is exactly 12 inches, 1 inch is exactly 2.54 centimeters, and 1 gram is exactly 0.001 kilograms. Quantities...

Purpose of the Study:

  • To introduce an accessible method for constructing a custom logic analyzer suitable for long-term, high-speed data acquisition in scientific research.
  • To provide a cost-effective solution using readily available Field-Programmable Gate Array (FPGA) kits and personal computers.

Main Methods:

  • Development of a logic analyzer system based on a low-cost FPGA development board.
  • Utilization of an open-source toolchain for FPGA design and implementation.
  • Data collection via standard software and post-processing using Octave scripts.

Main Results:

  • Successfully implemented a functional logic analyzer capable of continuous, long-term data acquisition with high temporal resolution.
  • Demonstrated the feasibility of using open-source tools and affordable hardware for advanced data acquisition tasks.
  • Provided sample FPGA design files and data processing scripts for ease of replication and modification.

Conclusions:

  • The proposed FPGA-based logic analyzer offers a practical and economical solution for scientific data acquisition needs, overcoming the limitations of commercial instruments.
  • The approach is adaptable for specific laboratory requirements, even for users with limited FPGA design experience.
  • Facilitates critical measurements in fields like telecommunications for worst-case jitter analysis.
