Refine the product and refine the service

In the era where brands and users are rushing towards each other, the real way to face users is to build by meeting their real needs

Establishing a positive relationship of reliance, more and more users are willing to establish fixed partnerships with certain intended brands, which not only enables products to

The brand owner sees their own needs and attitudes, and hopes that the brand can provide them with a smooth application experience. precisely because

In this way, refining products and services can create a sense of dependence on the brand among users, thereby increasing the brand

Viscosity is an opportunity to manage a brand and establish good user relationships.

Quality based value regression, activating consumption、Experience first

The overall economic environment remains sluggish, and the consumer market lacks vitality. Some users' consumption habits have shifted from blind worship to rational choice, indicating the awakening of consumption concepts. Domestic products are ushering in an opportunity to redefine their brand value and market position. Produced independently by Chenhang CompanyScienhome C18 250*4.6near30Due to its excellent repeatability stability and favorable prices, it has gained more popularity among users.At present, this chromatographic column supports user trial and can replace imported chromatographic columns of the same specifications.

C18Application scenarios and temperature control of chromatographic columns

Applicable fields:

Scienhome C18The chromatographic column has high hydrophobicity and longer carbon chains, which makesC18The retention time of the chromatographic column is relatively long, therefore it has high resolution when facing the separation of complex samples, and satisfactory separation performance in reverse phase chromatography, especially suitable for the analysis of compounds such as long-chain fatty acids and drug components.C18Chromatographic columns are used for the analysis of compounds such as long-chain fatty acids and pharmaceutical components in fields such as environmental science, pharmaceutical industry, and chemical analysis.

Temperature control:

temperature toC18The separation performance of liquid chromatography columns has a certain impact. During use, the column temperature should be kept stable to avoid excessive temperature fluctuations. Generally speaking, the column temperature should be controlled within25℃–40Between ℃.

By selecting and controlling the temperature of the column temperature box reasonably, the stability and separation efficiency of the chromatographic column can be improved, thereby ensuring the accuracy and reproducibility of the analysis results.

C18Cleaning and maintenance of chromatographic columns

During use, the chromatographic column should be regularly cleaned to extend its service life. Usually, after each use, the chromatography column should be rinsed with an appropriate solvent to remove residual samples and their impurities. If not in use for a long time, the chromatography column should be cleaned and stored in a suitable solvent.

Try to add a protective column at the front end of the chromatographic column and clean it regularly. Protecting the column can prevent contamination and blockage of the chromatographic column.

（Scienhome C18Protective column)

Some users choose to install online filters before the chromatographic column, and the pre column filter sleeve is equipped with a fixed aperture sieve plate inside, which mainly functions to intercept impurities larger than the sieve plate aperture. The sieve plate can be cleaned regularly with ultrasound and reused. If the blockage is severe, replace the sieve plate with a new one, but it can only prevent blockage, not pollution.

Local services, reducing procurement costs, and responding more promptly

Chenhang Company provides customized services, fast after-sales response, and one-on-one technical services: it can directly communicate and discuss technical issues with application engineers. Compared with the lengthy technical support process of imported consumables, domestic consumables are more attractive in terms of technical support and easy replacement of consumables. And in the current high tariff environment, the cost-effectiveness of domestic substitute consumables is further highlighted, reducing procurement costs, shortening delivery cycles, and providing customers with convenient service experiences. We have been taking action!
