The Goldwater Environmental Laboratory (GEL) is a shared-use facility that provides multiple analytical services to assist researchers with analysis for chemical and ecological applications. The facility houses instrumentation for elemental analysis, surface area and porosity measurements, gas chromatography and isotopic analysis of greenhouse gases, ion chromatography, and both discrete and flow-injection options for analyses. GEL offers the TriStar II 3020, which is a fully automated, three-station analyzer capable of increasing the speed and efficiency of quality control analyses, with the accuracy, resolution, and data reduction to meet most research needs. In addition, the Thermo iCAP6300 ICP-OES is capable of rapid, simultaneous measurement of up to 70 elements in aqueous and organic solutions and is equipped with an auto-sampler with a capacity of up to 240 samples. The dual view design offers the flexibility of axial view for lowest detection limits and radial view for reduced interference; ideal for complex samples encountered in environmental research. GEL also provides a wide variety of support and equipment options to assist with sample preparation needs prior to analysis. GEL provides established procedures and protocols for all instruments and training assistance for researchers if requested. The experienced GEL staff are committed to providing quality and timely technical support to meet the analytical needs of researchers.
he PE 2400 is a conventional elemental analyzer. It operates by flash combustion of the specimen encapsulated in tin cups or disks whereby the specimen is completely combusted at a temperature of 1760 C.
The resulting gases are chemically scrubbed of the halogens (and of sulfur in the CHN mode) and are separated in a GC column. Detection is conducted by a thermal conductivity detector (TCD). Total C, H, and N are calculated with a precision of 0.1g.
Element ratios are more significant since they minimize instrument error. Molar element ratios may be reliably reported for up to three decimal places.
The iCAP is capable of rapid, simultaneous measurement of up to 70 elements in aqueous and organic solutions and is equipped with an autosampler with a 240 sample capacity.
The dual view design offers the flexibility of axial view for lowest detection limits and radial view for reduced interference; ideal for complex samples often encountered in environmental research.
Full frame imaging produces a picture of a sample and can be a useful qualitative tool in determining sample composition. Detection limits vary by element but are typically in the low to sub-ppb (ug/L) level.
The QC 8000 determines analyte concentrations using colorimetry to detect changes in color produced by the presence of analytes. It is typically used for automated testing of water, waste water and sea water. It is capable of measuring a wide range of analytes, given the appropriate manifold configuration and filter.
Currently we are able to measure: Ammonia, Chloride, Nitrate, Nitrite, Orthophosphate, and Alkalinity (methyl orange as a function of CaCO3). It can be expanded to measure dozens of other analytes as well.
The instrument is equipped with a 360 position autosampler for multiple sample analysis and an autodilutor for dilution of off-scale samples. It is capable of processing a combination of two analytes simultaneously.
This IC system determines analyte concentrations using chromatography columns and a pulsed electrochemical conductivity detector. It is typically used for automated testing of aqueous solutions. It is capable of measuring a wide variety of ions, given the appropriate eluant and analytical column. Currently, we are able to measure the major anions: Fluoride, Chloride, Bromide, Nitrate, Nitrite, Phosphate, and Sulfate as well as numerous other anions using an AS23 column. It can be reconfigured to analyze cations if required. The autosampler will accommodate up to 66 vials of 5 mL size, 88 vials of 0.5 mL size, or a combination of the two sizes.
Dionex ICS 2000
The ICS 2000 instrument is configured as a 2 mm system for high-sensitivity (sub-ppb) analysis. It is equipped with a potassium hydroxide eluent generator capable of gradient or stepped analysis and a column heater. These features offer improved peak resolution and sensitivity compared to the ICS 1000 system. Sample filtration via a 0.45 micron pore size filter (or smaller) is required.
Microwave Digestion System
This system can be used to digest or extract a wide variety of solid and liquid materials. Common applications include soils, minerals and rocks, sediments, sludges, plant and animal tissues, water, dairy. Commonly used to prepare samples for metals and nutrient (total N, P, S) analysis. Will accomodate 40 samples of 10-20 mL volume (including digestion reagents).
The Tristar II 3020 provides high-quality surface area and porosity measurements on solid materials by using the technique of gas adsorption.
The TriStar II is a fully automated, three-station analyzer capable of increasing the speed and efficiency of quality control analyses, with the accuracy, resolution, and data reduction to meet most research requirements.
The Shimadzu TOC-VC/TN analyzes liquid samples for total carbon (TC), inorganic carbon (IC), total organic carbon (TOC), and non-purgeable organic carbon (NPOC).
The TN unit allows for simultaneous TOC and Total Nitrogen (TN) analysis. A known amount of sample is introduced into the instrument and is either combusted (TC, TOC, NPOC) or acidified and purged (IC).
Carbon content is measured as CO2 by non-dispersive infrared gas analysis. The TOC-VC combustion analyzer has a measuring range of 1mg C/L to 25,000mg C/L with reproducibility of 1.5% CV.
It has a wide range of applications from ultra pure water to highly contaminated water. It is capable of multiple standard level and multiple constituent analyses in a
The AQ2 is a discrete analyzer that determines analyte concentrations using a colorimeter to detect changes in color produced by the presence of the analytes.
It is typically used for automated testing of water, waste water and sea water. It is capable of measuring a wide range of elements, given the appropriate flow cell, filter and manifold set-up. Currently we are able to measure: Ammonia, Chloride,Nitrogen (Nitrate, Nitrite, and Total Nitrogen), Phosphorus (ortho and total Phosphorus).
It is also currently capable of measuring acidity (thymol blue), alkalinity (methyl orange and thymol blue) and hardness of water as a function of CaCO3.
The instrument is equipped with an autosampler for multiple sample analysis. It can be expanded to allow performance other analyses if necessary.
