Dissolved solids
When the amount of dissolved solids in a sample (e.g., in waste or sea water, metallurgical digests) rises above a certain level (typically >3%), either the sample needs to be diluted or specific sample introduction components, which have a high solids tolerance, need to be used for analysis.
A typical high-solids sample introduction system is comprised of a parallel path nebulizer and wide bore torch center tube to prevent blockage due to crystallization of salts, either at the tip of the nebulizer or at the center tube. A baffled spray chamber is also used to reduce the matrix load (the amount of sample transported to the plasma) on the plasma.
Solid sample digestion
Because solid samples cannot be introduced into the plasma directly, they must be dissolved or digested into a solution. The main techniques used to dissolve solids are acid digestion and fusion.
When using fusion for sample preparation, complete digestion takes place. It also results in high solid content. As a result, sample dilution is needed to bring the total dissolved solid content into the working range of the instrument, reducing the method detection limit.
Acid digestion usually involves the dissolution of a sample in a hot acid, or a mixture of hot acids. Heating acids is performed on a hot plate, or by using a microwave digestion system that employs pressurized vessels to produce even higher reaction temperatures.

Q:
What are the common sample-related
ICP-OES problems that you see in labs?
A:
Many of the problems are
associated with all atomic
spectroscopy techniques.
They range from mistakes made
when preparing calibration
standards, sample mix-ups,
and samples that have analyte
concentrations that are higher
than the calibration range.
Then there are interferences.
In all ICP-OES analysis, one
particularly problematic source
of interference is spectral
interference.

What is the purpose of an Argon Humidifiers for ICP
Improve the Performance of Your Sample Introduction System with a Humidifier.
Argon Humidifiers are commonly used in ICP analyses involving samples with high concentrations of dissolved solids. It helps to alleviate salt deposits in the nebulizer and torch injector, allowing uninterrupted and maintenance-free operation.
