Bahan yang mungkin
Logik spektrum
Tugasan kumpulan berfungsi menjadi lebih yakin apabila beberapa jalur yang dijangkakan muncul bersama. Gunakan halaman ini untuk mencari puncak yang paling disokong, kemudian sahkan bahawa sampel yang sama menunjukkan corak yang koheren dan bukannya satu hit terpencil.
Penggunaan dunia sebenar
Halaman-halaman ini berguna untuk analisis bahan yang tidak diketahui, penjelasan puncak dalam laporan, penyelesaian masalah polimer, dan mengesahkan sama ada keluarga bahan calon adalah boleh dipercayai secara kimia.
Kesilapan biasa
- Menggunakan satu halaman kumpulan berfungsi sebagai keputusan bahan lengkap tanpa memeriksa spektrum yang lain.
- Dengan menganggap jalur yang paling kuat sentiasa menjadi yang paling diagnostik.
- Melupakan bahawa pemprosesan, bahan tambahan, penuaan, dan campuran boleh mengalihkan atau melebarkan puncak yang dijangkakan.
Nasihat pengesahan
Gunakan DSC, GC-MS, atau TGA apabila beberapa keluarga bahan berkongsi jalur yang serupa atau apabila kesan campuran menyebabkan tugasan FTIR tidak pasti.
