Chemistry Instrumentation and Electronics Facility (ChIEF)

The Chemistry Instrumentation and Electronics Facility (ChIEF) is committed to supporting the research community with experience in a wide range of electronics and instrumentation. We are able to troubleshoot and repair a wide variety of electronic equipment in use throughout the department, saving research groups from having to purchase expensive new products. We are also here to work on new electronic designs that can complement research groups' projects. The ChIEF staff has experience with:

Equipment and Software

ChIEF has the following advanced test equipment:

Agilent 33250A80 MHz Function / Arbitrary Waveform Generator
Agilent 34401A6.5 Digit Multimeter w/ microvolt sensitivity (2)
Agilent 53131A225 MHZ Universal Counter
Agilent E3631ATriple Output DC Power Supply (2)
Agilent MSO6104A1 GHz Mixed Signal Oscilloscope
BK Precision 889ABench LCR/ESR Meter
Fluke 189True RMS Multimeter (2)
Leader LBO-516100 MHz Oscilloscope (student use)
Tenma 72-50165 MHz Function Generator (student use)
Weller WRS3000>Soldering / Repair station
Weller WSLSoldering station w/ ESD protection (2)

The variety and bredth of equipment available allow us to power, troubleshoot, and repair a variety of applications. The mixed signal oscilloscope allows simultaneous measurement and display of 16 digital channels and/or analog signals. It can be directly connected to the internet for remote data collection, or data can be saved on USB memory sticks. It is an essential piece of equipment for troubleshooting complex systems.

Although this equipment is not currently available for general use, it can be signed out for short periods of time. We also have a couple of general purpose soldering irons that can be checked out as well.

Software We Use

dsPIC v24/30Digital Signal Processing development
LabVIEW v8.20Graphical programming development
MPLAB IDE v7.50PIC Microchip Development Environment
Nios II IDE v5.1Soft Micro-processor Development Environment
OrCAD Capture CIS v15.7Schematic Capture
OrCAD Layout v15.7Printed Circuit Board (PCB) Layout
OrCAD PSpice A/D v15.7Analog & Digital Circuit Modeling and Simulation
Quartus II v5.1FPGA Design Software

Experience and formal training allow for efficient design, modeling, and layout of circuit boards for all types of applications.

Repair Capabilities and Inventory:


ChIEF has extensive experience in trouble shooting and repair of advanced research equipment. We have moved away from repair of small items that can be readily replaced (stirrers, heaters, etc) and are concentrating on saving research groups from having to replace expensive experimental equipment when possible.

We have some inventory of electronics components (resistors, capacitors, switches, etc), but due to the large number of electronic and electrical components available today, we are only able to stock the most common devices. On this page are links to typical vendors that we use, and we suggest you check their websites for the parts you may need.
