What is hybrid micellar liquid chromatography primarily used for in the study?
|
To detect commonly used pesticides in vegetables. |
|
Hybrid Micellar Liquid Chromatography (HMLC) เป็นเทคนิคที่ใช้ในการวิเคราะห์สารตกค้างของสารเคมี โดยเฉพาะอย่างยิ่ง สารกำจัดศัตรูพืช (pesticides) ในอาหาร เช่น ผักและผลไม้ ไม่ได้ใช้เพื่อ:
• เพิ่มการผลิตสารเคมี
• ส่งเสริมการขายสารเคมี
• ศึกษาการเติบโตของพืช
• วิเคราะห์พันธุกรรมของพืช |
ในงานวิจัย HMLC ถูกใช้เพื่อตรวจหาและแยกแยะ สารกำจัดศัตรูพืชที่ใช้กันทั่วไปในผัก ซึ่งเป็นส่วนหนึ่งของการควบคุมคุณภาพและความปลอดภัยด้านอาหาร |

Which pesticide was found most commonly in the vegetable samples?
|
Chlorpyrifos |
|
In studies involving pesticide residue analysis in vegetables, particularly using techniques like Hybrid Micellar Liquid Chromatography, Chlorpyrifos is often reported as the most commonly detected pesticide due to its widespread use in agriculture for pest control. |
