Coulometric (coulometry) principle, ideal for trace-level testing; 5-inch color touchscreen with smart operation, automatic result calculation, and freely configurable sample IDs; complies with multiple national standards and suits virtually every industry.

When measuring moisture with a Karl Fischer analyzer, most samples can be added directly to the generator cell/titration cell for simple, accurate testing. Some samples, however, cannot be added directly because their moisture is not released naturally or they undergo side reactions with the Karl Fischer reagent — for example powders, granules, pastes, and oxidizing inorganic salts.

For samples that cannot be added directly to the cell, pairing the WKT-V2 Karl Fischer oven for gas-phase extraction is the perfect solution. The sample is placed in a vial and moved onto the oven, heated to a specific temperature (up to 300˚C), and the moisture is extracted and carried into the cell by dry air or nitrogen, then measured perfectly.

Founded in 2011, Qingdao Shuangyuan Taihe Pharmaceutical Co., Ltd. is a Sino-US joint venture high-tech enterprise headquartered in Pennsylvania, USA. The plant covers an area of 20,000 m2 with a building area of 5,000 m2 and employs more than 60 professional and technical personnel.

The company possesses the major synthesis technologies in the peptide field (solid-phase synthesis and liquid-phase synthesis) and has accumulated extensive experience in directed cyclization, phosphorylation, methylation, isotope labeling, and conjugation. The company has imported multiple sets of advanced instruments and equipment from abroad, including the Tetras multi-channel synthesizer, CS Bio synthesizer, PSI600 synthesizer, 50L automatic synthesizer, 150 and 300 DAC systems, Agilent HPLC, GC, LC-MS/MS, Shimadzu LC-MS, and PE elemental analyzer. The company has reached pilot-scale production capacity in peptide synthesis, purification, and lyophilization.

Shuangyuan Taihe is headquartered in Philadelphia, USA. Qingdao Shuangyuan Taihe Pharmaceutical Co., Ltd. is its Qingdao branch, mainly responsible for business in China and peptide production.

The company has established a strict quality management system. From raw material intake, production process control, and product release to instrument management and personnel training, everything follows GMP requirements.

Excellent management concepts, strong R&D resources, a rigorous quality system, and an outstanding professional technical team will make Shuangyuan Taihe a world-class peptide drug R&D base.
