Material Preparation and Test Method Details The analysis method requires sample preparation with specifc grinders and grinding pads, followed by testing with the Z-200 C+. We utilize a handheld grinder operating > 5, 000 rpm, with minimum 50 grit Al2 O3 or ZrO ceramic grind pads. The same grinding recommendations as spark OES are employed. For L-grade analysis, change the grind pad more frequently, say every 5 materials or so. If you grind a high carbon material, it is best to change the grind pad before moving to a low carbon material, due to cross contamination.
Details of the Test Method Defnitions: A “test” is a single test of the material with the Z LIBS analyzer. For each test, the laser rasters to six different locations on the alloy material and averages the result from each of the six locations. This requires 3 seconds. The purpose of the six tests is to average out any local inhomogeneities in the alloy composition because the laser beam is less than 100 um in diameter. Rastering is typical with LIBS, but not with spark OES because the OES burn is much larger than the laser burn. A “result” is a fnal answer that consists of typically two or three LIBS tests which are automatically averaged by the analyzer software. Each test takes 3 seconds, so a result is typically 9 - 15 seconds depending on the number of tests averaged.
As mentioned earlier, operators may run the Z-200 C+ in a manual mode or a selection of automated modes. Manual operation performs a pre-fush, pre-burn and then 3 consecutive 3s tests. The number of tests is user settable. Each test is shown on the display, along with the running average. The user can tap on one or more tests to remove them from the averaging. The user may also pull the trigger to add additional tests. Experienced OES operators with good sample prep typically run 2 or 3 tests after the pre-burn. Two tests are used to confrm the frst result, or 3 tests to make an average. Less experienced operators are encouraged to star out with the automated test rejection feature. There are two automated testing options: High/low rejection and rejection based on variation at each of the six raster points. High/low rejection requires fve tests. It rejects the highest and lowest tests and produces an averaged of the remaining three tests. Note: SciAps will incorporate additional rejection methods based on user input. Precision-based rejection is even more suited for inexperienced operators. It’s a useful approach to identify insufcient sample prep or contaminated grind pads. As noted during a 3 second test, the laser collects spectral data from six different locations. For precision-based rejection the Z rasters the laser to six discrete positions during a test. The FPGA engine and Android processor analyzes the spectral data and compares carbon intensity ratios from the six locations. The Z rejects a test if the standard deviation in carbon intensity ratio from the six locations exceeds a predetermined threshold. The software prompts the user for additional tests until the required 3 good tests are achieved. For less experienced operators, especially regarding the rigorous sample preparation required for carbon testing, the automated rejection setting is a great option. Better sample prep means less tests rejected.
