Which of the following roles does a lab analyst NOT typically perform?

In the context of laboratory work, a lab analyst primarily focuses on conducting sample analyses, documenting results and procedures, and ensuring compliance with established standards. These functions are vital for maintaining the quality and integrity of the lab's operations and the accuracy of the data produced.

Developing new laboratory instruments, on the other hand, is usually outside the typical responsibilities of a lab analyst. This task is more aligned with research and development roles, where engineers or scientists are involved in designing and creating new equipment and technologies. Lab analysts generally operate existing instruments and methods to analyze samples, rather than being involved in their development from concept to implementation. This delineation of responsibilities highlights the analyst's focus on analysis, quality control, and regulatory compliance, rather than on instrument invention or enhancement.
