摘要
目的探索被洗涤后衣物上潜血痕迹的发现方法。方法用联苯胺法、鲁米诺法和新型仪器TL-445激光生物检材发现仪寻找不同织物上不同洗涤强度的潜在血迹。结果联苯胺仅能发现部分纯棉织物上潜血,鲁米诺能显示全部纯棉织物上血迹,TL-445激光生物检材发现仪能显示所有纯棉、纯化纤织物上血迹。结论用TL-445激光生物检材发现仪检测相比联苯胺法和鲁米诺法更适合洗涤后织物上潜血痕迹的发现。
Objective To explore a effective method for detecting latent bloodstains on washed fabrics. Methods Blood- stains on cotton fabric and synthetic fabric washed with different intensity were detected by Benzidine test, Luminol test and TL- 445 laser biology sample detect instrument. Results Some of latent bloodstains on cotton fabrics were detected by Benzidine test, all stains on cotton fabrics were detected by Luminol test, and all stains on cotton fabrics and synthetic fabric were detected by TL- 445 laser biology samples detect instrument. Conclusion TL-445 laser biology samples detect instrument is more sensitive to find latent bloodstains on washed fabrics.
