chemometric techniques for quantitative analysis

Kỹ thuật định lượng dựa trên phương pháp hóa học được sử dụng để rút ra thông tin có thể hành động từ dữ liệu hóa học. CLS, một phương pháp hồi quy tuyến tính, nhằm mục đích tìm mối quan hệ tuyến tính giữa dự đoán (thường là một thuộc tính vật lý của mẫu) và các biến quan sát được (thường là một quang phổ). ILS là một phương pháp thống kê đa biến dựa trên hồi quy thành phần chính tìm cách liên quan dự đoán đến một tập hợp các biến quan sát được được giải thích theo phương sai mà không sử dụng thông tin nồng độ của mẫu. Với nhiều công cụ đo lường có khả năng tạo ra dữ liệu cực kỳ nhanh và chi phí thấp, phương pháp hóa học hiện được sử dụng rộng rãi trong cả các phòng thí nghiệm phân tích và xử lý.
