|1. Hazard to lab technicians||4. Increased number of rejects|
|2. Damage to instrumentation||5. Bad data|
|3. Reduced efficiency in testing||(Garbage In = Garbage Out)|
A technician has to spend time picking out foreign materials which slows down the testing process. Additionally, handling samples that contain metal is a hazard for the technician and can cause significant damaged to hundred thousand dollar instrumentation. Samples that have not been ginned or that are poorly ginned will be rejected by the test instruments. Poor sample preparation does negatively impact the capability of instrumentation in providing accurate quality information.
