"During the project, there is some sampling schedule problem from our side, but Yang worked well with us. We really appreciated the effort."
"Yang Li at Advanced Analytical Testing Services was extremely professional and timely. He kept me up to speed with the HPLC analysis requested and even tested the sample twice to confirm the findings. Really impressed with the level of service as well as the final report submitted. I recommend anyone looking for accurate HPLC use Yang Li's services. Thank you, PSP Research"
