Ammonium — Puncak serapan FTIR dan tugasan
Ini adalah nombor gelombang FTIR ciri di mana Ammonium cenderung menyerap, disusun dari literatur yang diterbitkan dan disusun berdasarkan bukti sokongan. Setiap tugasan dapat dikesan ke sumber (DOI) dan disahkan silang terhadap 130,000+ spektrum rujukan dan graf pengetahuan kami.
Backed by 8 cited sources
Jawapan pantas
Ammonium biasanya ditetapkan dengan mencari kelompok berulang puncak ciri dan bukan satu nombor tepat buku teks. Jadual di bawah menunjukkan di mana literatur paling kerap meletakkan kumpulan ini dalam FTIR, yang disusun mengikut bukti terkumpul.

Menunjukkan 30 puncak terbaik disokong daripada 132 jumlah untuk Ammonium.
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.
