The Significance of Routine Maintenance of the Interface Cones

77

The entire samples and skimmer cones serve the same purpose regardless of the ICP-MS producer or design. They are used to separate different pieces in the atmosphere from the detectors or mass filters at a high volume. However, the crucial dimensions al all are critically the same pieces.

When it comes to the cones, they have been designed with insignificant dimensions. These dimensions include particular specifications depending on the design of the mass spectroscopy. The authentic cone design may vary greatly depending on one lab instruments manufacturer to another.

The area that needs maintenance is mainly in the analytical zone since it displays the most vital differences. Together with the sample type, these variations contribute to the rate at which salts and oxides are accumulating in and out of the cone orifice. They are also affecting the rate of cone degradation and influencing the cleaning methodology.

In the final analysis, the data quality is diagnosis equipment to determine when to clean or change the cones. But, if you notice a significant build-up on the cone, and it seems to be including the orifice, cone elimination and cleaning are warranted. The entire instruments manufacturers are prescribing a daily routine to assess the system’s status before the analytical run. These quick and simple tests can also be used to determine the condition of the cone qualitatively.

Read on and learn more about how the notice when the cones start to impact the instrument’s performance negatively.

Blocking or Blocking

As oxides and salts cones are building around in ICP MS Conesthey will be changing the electrical characteristics and gas flow dynamics on the cone interface. Symptoms may include decreased sensitivity and signal stability. In severe cases, the change in signal response may occur across the mass range due to pressure alterations.

Code degradation

Whether from incorrect use, prolonged use, aggressive matrices, or blunt force trauma, future cones will be degrading beyond the required limits. Proper cleaning and careful handling will typically allow many months of operational use from each set of Pt cones and Ni cones. Some widespread symptoms of cone degradation are reduced oxide levels, double-charged species, and in severe conditions, poor vacuum levels.

Contamination

Identical to other components of the sample introduction system, Sample cones are typically affected by specific memory impact. This is primarily from components like boron, lithium, and magnesium. This mainly works well when trying element trace analysis of samples that were in solution and highly concentrated in the past. In many occurrences, memory results are due to the sample introduction system. For that reason, an in-depth assessment of the entire prospective sources of memory effects should be conducted.

Cleaning ICP MS Cones with a cu base needs a little modified technique to prevent it from unduly wearing and tearing the cone’s cu part. Especially where it connects with the Ni or Pt tip. The metal cleaner will be attacking the Cu and may degrade the weld between the two metals in the future.Hopefully, the materials outlined in this article will help novice ICP MS users.
