Elemental and Ion Analysis
Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES) is an analytical technique used for the detection and quantification of trace metals. It uses inductively coupled plasma to excite electrons from their orbitals resulting in electromagnetic radiation characteristic of a particular element.
Incredibly sensitive UV and visible light detectors and instrument linearity over six orders of magnitude allowing detection limits from the low ppb range up the % range.
This powerful method allows multi-element detection in complicated aqueous mixtures and coupled with acid digestion can be applied to a range of mediums. The Optima delivers robust and sensitive elemental analysis on the most difficult matrix with remarkable reliability.
Sample preparation for ICP-OES often requires acid digestion of solid samples. At GAF our highly experienced team offers a range of digestion techniques from traditional open vessel Kjeldahl digestion to microwave digestion with the Milestone Microwave Digestion Service.
Take the time to discuss with our analysts the best method for digesting your samples.
Microwave Digestion
Microwave digestion is a common technique utilised in elemental analysis to dissolve solid analytes into acidic solution. The system utilises closed Teflon chambers to house the digestion materials during the heating process by microwave. The combination of high pressure and temperature create the best method for fast, repeatable digestion performance resulting in better LoD and easier clean-up. Typically this method of sample preparation is used to prepare samples prior to analysis by ICP-OES.
Hot Block Digestion
Hot block digestion options are also available. Take the time to discuss with our analysists the best way to prepare for analysis.
Recent development in our ICP-OES capabilities allow the direct analysis of organic matrix.
ICP-OES Elemental Analysis
This standard analyte suite has been developed to offer a collection of elemental standards with working linear ranges that meet clients needs. ICP-OES is characterised by displaying an extremely linear relationship between concentration and counts, that being said we recommend the calibration range cover 80% of the analytical response. Discussion with your analyst before analysis should cover this.
| Elemental Suite | linear range (ppm) |
|---|---|
| 1. Na, K, Ca, Mn, Mg, | 1, 10, 100 |
| 2. Cu, Zn, Si, Al, B, Se Co, Mo | 0.1, 1, 10 |
| 3. Hg, As, Pb, Cd, Cr. | 0.1, 1, 10 |
| 4. S, P | 1, 10, 100 |
| 5. Fe | 1, 10, 100 |
Note: ICP-OES is an analytical technique that can be heavily affected by matrix effect, and memory effect can be particularly problematic. The quality of the analytical results can be heavily influenced by instrument set up to mitigate these issues. It is essential, prior to analysis you have an honest discussion about the nature of your sample.
Precious Metals:
We have a range of precious metals standards available for quantitative analysis. Typically these digestions are completed in Aqua Regia, to stabilise these precious metal ions in solution, prior to analysis with ICP-OES.

Currently the Gallery Plus is geared for the following analysis. Don't hesitate to contact our operators through iLabs to discuss the following instrument capabilities.
Gas Chromatography
Gas Chromatography is a method in which the sample mixture is vaporized and injected into a stream of carrier gas (such as nitrogen or helium) moving through a column containing a stationary phase composed of a liquid or particulate solid and is separated into its component compounds according to their affinity for the stationary phase. A range of detectors are then utilise quantify and identify the analytes of interest.
The GC-2010 Plus enables reliable, high-precision trace analysis with high repeatability. In addition, rapid oven cooling and back flush technology shorten analysis time greatly for significant improvements in productivity.
Features high sensitivity and ultra-fast performance, enabling trace analysis at the level of parts per trillion. This instrument is the most recent state-of-the-art gas chromatograph/mass spectrometer offered by the Shimadzu Corporation. Components that cannot be analysed by conventional scan or SIM modes are easily identified and quantified at trace levels in the presence of complex matrices using the Multiple Reaction Monitoring (MRM) mode. This instrument is particularly well suited for the analysis of trace compounds in complex matrices.
