Agilent Inductively Coupled Plasma Mass Spectrometer ICP-MS 7850

（1） Product features:

Standard operating procedures and comprehensive development methods for regulatory and routine analysis can save you weeks of method development and documentation time.

The Ultra High Matrix Injection System (UHMI) can directly analyze samples with a total dissolved solids content of up to 25% without dilution, thereby reducing sample pretreatment time.

The helium collision cell and half mass correction can eliminate the tricky interference of multiple atoms and double charged ions, avoid reducing data quality, and reduce the need for high cost sample re measurement.

High matrix samples can be determined without the need for matrix matching calibration standards. Hydrochloric acid can also be added to stabilize important elements such as Hg, Ag, Mo, etc. without introducing new interference.

IntelliQuant can identify abnormal sample matrices and obtain complete elemental spectra for each sample. Multiple display modes, including the periodic table heatmap, can help you easily identify constant or unknown elements with abnormal concentrations.

Outlier Condition Format (OCF) can highlight results that are out of range or do not meet testing requirements, thereby reducing the time for busy or inexperienced ICP-MS operators to review data. Reminder information can be configured according to different needs.

The Early Maintenance Feedback (EMF) function uses sensors and counters to determine when the system needs maintenance. Traffic signal color warning ensures that you do not miss any maintenance tasks, but also do not perform maintenance too frequently.

ICP Go is a browser based optional user interface for mobile devices that simplifies the setup and control of regular sample batches, making it ideal for ICP-MS operators who travel back and forth.

The analyzer kit for specific methods includes ICP-MS hardware, software, consumables, professional services, and documentation, ensuring that you can start running samples within weeks without spending months on regulatory method development, optimization, validation, and documentation.

（2） Working principle:

1. How to obtain accurate results for high matrix samples

High matrix samples can cause signal drift and suppress plasma, resulting in inaccurate results that require repeated analysis. The ultra-high matrix injection system of 7850 uses argon gas flow to dilute the sample. Samples with TDS up to 25% in the matrix can be analyzed without time-consuming and error prone manual dilution.

Meanwhile, the helium collision pool and half mass correction of 7850 can automatically eliminate interference from multiple atoms and double charged ions. These features not only simplify method development, but also avoid common issues that lead to measurement failures.

2. How to obtain accurate results for high matrix samples

Special sample matrices may cause unexpected problems. Understanding the composition of the sample can avoid many problems and costly repeated measurements of the sample. The IntelliQuant software function uses full scan mass spectrometry to perform comprehensive component analysis on each sample. The results are displayed in the form of a heatmap, allowing you to quickly identify unexpected or abnormally high levels of elements as well as sample pre-processing errors. This information helps to confirm dilution factors and calibration ranges, and identify matrix effects that may affect internal standard elements.

3. Conduct appropriate maintenance at the appropriate time

Insufficient maintenance can affect instrument performance, leading to unplanned shutdowns and wasting valuable time. But too frequent maintenance can also waste time, increase consumable costs, and not bring any practical benefits. Early maintenance feedback uses sensors and counters to determine when maintenance is needed based on instrument usage. Traffic signal color warning ensures that you do not miss any maintenance tasks, but also do not perform maintenance too frequently. ICP-MS with ideal maintenance can provide better performance, saving time and money for the laboratory.
