Advantages Disadvantages
Pre-column Derivatization
Method appropriate for higher-sensitivity analysis
of a somewhat limited variety of samples, such as
purified amino acids
• Consumes less reagent
• Simpler instrument configuration
• Allows increasing sensitivity
• Wide availability of derivatizing reagents allows selecting the
reagent best suited to the type of detector (such as UV, VIS, or RF)
• Allows using rapid reversed-phase chromatography
• Derivatization reaction efficiency is affected by
sample matrix
• Reaction products are often unstable and can
often affect quantitation results
Post-column Derivatization
Once the reaction system is optimized, it can be
used for a wide range of samples, including
fermentation extracts, making it suitable for
routine analysis with excellent quantitation
performance
• Reactions can be automated
• Outstanding quantitation capability and reproducibility
• Because sample components are separated in the column before
the reaction, it is not affected by the sample matrix during reaction
with the derivatizing reagent
• Difficult to use for high-sensitivity analysis
• Relatively high reagent consumption
• Limited variety of derivatizing reagents can be
used
• Cannot use rapid reversed-phase
chromatography

Giải pháp phân tích aa tự động từ sykam
So sanh tao dan xuat trươc và sau cot va LC –MS, huynh quang
Do nhay, truoc cot nhay hơn voi huynh quang
Đa lượng là nhiều, vì trong thức ăn amino acid nhiều
Sau cột, Huỳnh quang nhạy hơn, làm đa lượng, ko cần nhạy cao tới huỳnh quang, cần nhiều dung môi, chỉ để
dc 3 ngày, măc tiền hơn nin,
Hitachi nhất, nhì sykam
Để hóa việt,
633, còn đang thử nghiệm
Áp xuất thấp, tốc độ dòng thấp, pH thay đổi từ thấp len cao do chạy gradient
Nhu cầu cuộc sống về amino acid, nhu cầu sản xuất
Đạm:
Amino acid khác acid amine
Nhóm chất bổ
Amino acid: Nhu cầu và các giải pháp phân tích tối ưu
Noi them vè IC, HPLC, sắc ký điều chế của sykam
Có cung cấp giải pháp xử lý mẫu, sẵn bộ kit pha động chạy và hãng sẵn sàng chuyển giao công thức
Khả nawg chiu pH 0-14, máy chịu được
Khả năng tách của cột tốt, trao đổi cation mạnh
Những cột amino acid hầu hết là shodex, trừ hitachi nhưng mắc gấp đôi
