STI601 High Performance Liquid Chromatography (Gradient) Introduction: The STI601 high-performance liquid chromatography instrument is the latest high-performance liquid chromatography instrument independently developed and produced by our company. Its self-priming one-way valve ensures the stability of pump flow, further improving performance stability. The floating dual plunger rod and sealing ring technology can extend the service life of the sealing ring. The automatic cleaning device is easy to operate, while reducing damage to the plunger rod and lowering costs. STI601 has added a user-friendly LCD touch screen with a more precise design, high cost-effectiveness, and stable performance. It can be widely applied in various analytical fields such as research and development, pharmaceutical inspection, food testing, chemical analysis, environmental monitoring, etc. Features: 1. The gradient elution internal software can be self controlled; 2. By closing the control through external contacts, it is easy to change the purpose of the pump; 3. The control method is flexible, and the pump parameters can be controlled by either the pump panel or the system under different requirements; 4. Power on self-test, internal safety alarm and automatic fault diagnosis function of the instrument; 5. The optical path system adopts precise positioning structure and unique heat dissipation technology, efficient optical system and digital filtering; 6. Light source: optional deuterium lamp and tungsten lamp, deuterium lamp warranty life of 1000Hrs; When replacing the light source, there is no need to adjust the optical axis, making maintenance easy; Real time display of sample and reference cell energy, facilitating the determination of light source and flow cell status; 9. Zero adjustment function: The absorbance can be reset to zero by the panel or automatically reset by the program software; 10. Wavelength adjustment function: It can be controlled by the keyboard panel or set by program software. The fully enclosed integrated photoelectric detection element can select or change the wavelength without any mechanical adjustment Technical Specifications: Liquid transportation principle: Double plunger series reciprocating mode, automatic pulse suppression system, and equipped with solvent compression factor program, which can automatically compensate for flow rate and achieve more accurate liquid transportation Maximum conveying pressure: greater than or equal to 6000PSI (approximately 42MPa or above) Flow velocity accuracy: 0.1% Flow rate range: (0.001-100000) mL/min with small increments of 0.001mL/min Piston rod cleaning: Automatic plunger rod cleaning without the need for additional equipment to protect the plunger rod Security: Equipped with power on self-test, high and low voltage alarm and protection functions Mixing principle: high-pressure mixing Number of mixed liquids: greater than or equal to 2 yuan Degassing device: Both internal and external degassing can be used Light source: Deuterium lamp (tungsten lamp optional) Wavelength range: 190 to 720nm Wavelength accuracy:<± 1nm Wavelength reproducibility:<± 0.5nm Bandwidth: less than 5nm Noise:<± 2.5 * 10-5AU (under specific conditions) Drift:<± 2.5 * 10-4AU (under specific conditions) Flow pool volume: 10ul Absorption range: 0.01AU/V-10AU/V (ten levels in total) Function: With fixed-point wavelength measurement, hardware embedded detector for data processing, and direct acquisition and processing of digital signals Chromatographic column: C18 column, with protective column Column temperature chamber: 10 ° C to 100 ° C (0.1 ° C increments) at room temperature Workstation: Chinese operating software, supporting operating systems such as WIN9X/XP/2000/2003, hardware embedded detector, direct acquisition and processing of digital signals Injector: VI-11 manual injection valve (with remote trigger switch), equipped with 20UL quantitative loop
