펩티드와 단백질의 가수분해물중의 아미노산을 정성?정량분석
(1) Column Unit 1) Heating and cooling is effected by peltier elements or equivalent 2) High resolution PEEK material analytical column with finger-tight fittings. 3) Temperature control : ± 1 ℃ or better 4) Column temperature is gradient programmable from 30 to 70 ℃ or wider (2) Physiological fluid analysis time (lithium) : 120 mins or less (3) Regents and Buffers : Microgradients and stepwise gradients for five buffer and one regeneration solution, one ninhydrin reagent and flushing water or more. (4) Pumping System 1) The Ceramic pumps offer metal free pumping surfaces ensure constant flow, low pulsation and eliminate corrosion. 2) The pumps give total control of the flow rate via the control software. 3) No need check flow rates. 4) All the pumps have an automatic piston flush system. (5) Detection System 1) Photometer : Single flow cell with 440 nm and 570 nm detection for ninhydrin detection method. Tungsten halogen lamp with precision relay lens optical system. 2) Reaction coi l : a. High temperature, solid state system controllable from 50 to 145 ℃ or more b. Safety over-temperature cut-out c. Coil flushing automatically occurs after power fail to minimise coil blockages d. Reaction coil temperature control accuracy : ± 1 ℃ or better 3) Detection Limit a. Ninhydrin : less than 9 pmole 4) Reproducibility of retention time : 1 % CV
