Parallel mode - a 100% increase efficiency by sharing autosampler system, a dual-ternary system analysis can be done both at the same time. Greatly improves the efficiency and throughput of the instrument. Line mode - running time by 20 to 50 percent left pump for analysis (orange), the right pump for column regeneration (blue), by sharing autosampler and detector systems, saving column flushing and balance time, phthalates 16p, increase detection speed. Front-line sample preparation - leap conventional solid-phase extraction method from five hours to 20 minutes require multiple manual operation, and it takes time to process the samples, it is difficult to ensure good reproducibility and satisfactory recoveries . Double three yuan system can sample line solid phase extraction, purification or pre-concentrate. Sample pre-treatment can be completed within 20 minutes and analyzed directly. LC-3000 infusion pump performance characteristics steady flow pump LC-3000 to ensure that all mechanical components corresponding processing accuracy; electronic components aspects of using high-quality chips and imported motor, while using special cushioning technology designed and developed can achieve low pulse steady infusion. Static Motor own patented design of the control circuit, phthalates, ensuring a constant flow of high-precision, pvc phthalate, reliable experimental data provides the necessary guarantees. Adaptability thanks to our own patented design floating pump seals and self-cleaning device structure, the user can easily wash the plunger rod, especially when using a high concentration of buffer solution as mobile phase, the phthalates 7p, it can be washed off from the crystallization buffer salt, to extend the plunger rod and seal life. High pressure long life and easy maintenance unit member one-way valve, seals and plunger rod, etc. are made of foreign professional manufacturers of brand-name products, so LC-500A constant high pressure pump longer life. Also simple pump and compact structure, the use of floating head design, the user can very easily replaceable parts relevant unit. pvc phthalate, phthalates, rohs2.0 tester is supplied by Shenzhen Huayi Technology Co., Ltd. Four Seas. Shenzhen Huayi Technology Co., Ltd. Four Seas (huayi-universal.com) (www.huayi-univerasl.com) strong, credible, analytical instruments in Shenzhen, Guangdong and other industries has accumulated a large number of loyal customers.
