Chromatographic maitiro mune forensic texicology

Forensic vanexicologists vanoshandisa akasiyana marmatography maitiro, zvichienderana neyekuongorora ivo vari kuyedza:

Gasi Chromatography (GC): Gasi Chromatography inoshandiswa zvakanyanya kuongororwa kwezvinhu zvisina kunaka senge doro, uye zvinodhaka, uye zvisina kujairika organic makomendi. Kuti ushandise GC zvinobudirira, samples dzinofanira kutanga rave vaporized vasati vaunzwa muchikamu chekuparadzaniswa kubva pakuparadzaniswa nemusiyano mukumanikidza kana kushamwaridzana kwayo. Viumus dzakasarudzika dzakagadzirirwa zvakananga kuti chiitiko ichi chave nechokwadi chekuenzanisa jekisiki nekurasikirwa kushoma panguva iyi.
