FLOW PATH WASHING METHOD OF AUTO SAMPLER AND FLOW PATH WASHING APPARATUS OF AUTO SAMPLER - A simplified explanation of the abstract

This abstract first appeared for US patent application 18038273 titled 'FLOW PATH WASHING METHOD OF AUTO SAMPLER AND FLOW PATH WASHING APPARATUS OF AUTO SAMPLER

Simplified Explanation

The patent application describes a method and apparatus for washing a flow path in an auto sampler, where a cleaning fluid is supplied to switch between different flow paths for sample aspiration and washing.

  • The control unit changes the flow velocity of the cleaning fluid based on washing information corresponding to different measurement items of the sample.
  • The washing information includes patterns for washing the nozzle and sample loop based on the measurement items to be analyzed.

Potential Applications

This technology can be applied in laboratory settings where automated sample analysis is required, such as in pharmaceutical research, environmental testing, and food safety monitoring.

Problems Solved

1. Ensures thorough cleaning of the flow path between different sample measurements. 2. Reduces the risk of sample contamination and cross-contamination during analysis.

Benefits

1. Improved accuracy and reliability of sample analysis results. 2. Increased efficiency by automating the washing process. 3. Extends the lifespan of the auto sampler components by maintaining cleanliness.

Potential Commercial Applications

Optimizing Flow Path Washing Method for Auto Sampler in Laboratory Settings

Possible Prior Art

Prior art may include similar methods and apparatus for cleaning flow paths in auto samplers, but the specific feature of adjusting flow velocity based on washing information may be unique to this patent application.

Unanswered Questions

How does this technology compare to manual cleaning methods in terms of efficiency and effectiveness?

Automating the washing process in an auto sampler may save time and reduce human error, but it would be interesting to see a direct comparison of results between manual and automated cleaning methods.

What is the cost-effectiveness of implementing this technology in a laboratory setting?

While the benefits of improved accuracy and efficiency are clear, it would be valuable to understand the upfront and ongoing costs associated with integrating this technology into existing laboratory equipment.


Original Abstract Submitted

A flow path washing method and apparatus for an auto sampler in which, when a cleaning fluid supplied to a flow path which is switched between a first flow path including a nozzle for aspirating a sample and a sample loop for holding the aspirated sample, and a second flow path including a washing tub for washing at least an outer wall of the nozzle, a control unit changes a flow velocity of the cleaning fluid supplied between measurement of a first measurement item and measurement of a second measurement item based on washing information showing washing patterns corresponding to measurement items of the sample, including at least one of first washing information showing a washing pattern corresponding to the first measurement item of the sample and second washing information showing a washing pattern corresponding to the second measurement item to be measured subsequent to the first measurement item.
