Environmental Analytical Research Laboratory (EARL)

Lab Goals

  • Teaching Support: Hosting training course(Geol 540) to provide students an opportunity to learn lab skills and to gain experience using our laboratory equipment.
  • Research Support: To support scientific research and engineering design projects in environmental investigations.
  • Analytical Service: Providing reliable analytical service to our customers with best possible combination of convenience and cost.

Equipment

EARL houses an ion chromatograph, an atomic absorption spectrometer, a total organic carbon analyzer, sulfur analyzers and ancillary equipment to support teaching, scientific research and engineering design projects.

TOC Analyzer

Shiadzu TOC-V/SSM5000A

  • The sampling needle is optimized for sample extraction from highly-sealed vials and for sparging.
  • Changing analysis conditions or adding sample vials during analysis is simple. System operation and carrier gas flow can be automatically stopped on completion of measurements.
  • Creating multiple calibration curves and selecting the optimal curve for samples with significantly differing concentrations allows these samples to be analyzed in a single run.
  • Rinsing both external and internal surfaces of the sampling needle prevents carryover between samples.

OCP-OES

Agilent 5100

  • Start work sooner with the zero gas consumption VistaChip II detector that shortens warm-up time.
  • Measure your toughest samples with a vertical torch – from high matrix to volatile organic solvents.
  • Minimize interferences with our Cooled Cone Interface (CCI).
  • Achieve long term analytical stability with a solid-state RF system that delivers a robust plasma.
  • ICP Expert software and DSC technology. Powerful software algorithms simplify method development, improve accuracy, and extend your measurement range.

Microwave Digestor

CEM MAR-6

  • MARS 6 will automatically detect the type of vessel you are using, count the vessels, adjust the power accordingly, and perform the digestion for you.
  • iWave® is a contactless, in-situ temperature technology that measures the sample temperature of each vessel in real-time.
  • The MARS 6 temperature sensors are designed to meet USEPA temperature requirements by sensing the temperature to within ± 2.5 °C and automatically adjust the microwave field output power within 2 seconds of sensing. Temperature sensors are accurate to ± 2 °C.
  • MARS 6 units are capable of fiber optic, IR, and internal pressure control.

Ion Chromatograph

Dionex DX-120

  • The dual-column system allows switching between two sets of columns (column select mode) or between two eluents (eluent select mode). In the eluent select mode, the DX-120 can perform step gradients.
  • Excellent accuracy and linearity over a broad working range.
  • Efficient sweepout and low volume for low dispersion.
  • Reduced sensitivity to electrode surface conditions
  • Low electrode mass
  • Effective temperature compensation

Portable UV/VIS Spectrophotometer

Hach DR/2010

  • Uses proven Hach methods (many are USEPA1 approved or accepted) for colorimetric analysis of more than 120 common water quality parameters.
  • Stores and recalls data with new datalogging capabilities. Accurate data transfer by means of updated software. Reducesb data-reporting errors with powerful software designed to store up to 1000 readings. Helps meet GLP2 guidelines.
  • Increases productivity by eliminating manual calibrations and reagent mixing and measuring.
  • Rugged construction and portable battery pack enable analysts to take the DR/2010 into the field. Optional portable printer outputs results on site.

Portable Milti-Parameter Meter

HACH HQ40d

  • The Hach HQ40D portable multi meter is a two channels advanced handheld digital meter that takes the guesswork out of measurements.
  • Designed for your water quality applications measuring pH, Conductivity, TDS, Salinity, Dissolved Oxygen (DO), ORP and ISE.
  • The HQD portable meters connect with a wide range of Intellical smart electrodes addressing different parameters, sample types and operating environment for water quality, environmental and treatment process purposes.

Pocket pH Meter

Oakton PHTestr® 30

  • 0.01 pH accuracy along with dual pH and selectable C or F temperature display
  • A complete meter with key features at an economical price
  • Replaceable, double-junction electrode sensors save time and money
  • IP67-rated housing sits flat on the table and floats in water

Pocket ORP Tester

Oakton ORPTestr® 50

  • Double-junction pH electrode sensor is dependable, long lasting, and easy to maintain—ideal for use with sulfides, heavy metals, organics, Tris buffer, or protein solids.
  • Easy-to-replace sensor module lets you use the tester body over and over again.
  • Intuitive interface has self-diagnostic error messages, and battery-life and stable reading indicators.
  • Valox® body resists most chemicals and is rugged, dustproof, waterproof, and IP67 rated

Portable Conductivity Meter

Hach CO150

  • The CO150 conductivity meter is a full featured portable meter, which can be used for a wide variety of application in the field or the laboratory. Water quality acid base and other samples can be easily analyze for conductivity with the available conductivity probe.
  • The CO150 meter feature a microprocess or design which is complicated and time-consuming calibration and measurement procedure for a wide variety of application.
