Efficient ! 5 methods for cleaning chromatography sample vials

Oct. 21st, 2019
Chromatography is a powerful analytical technique that allows for the separation and identification of individual components within a sample. It is frequently used for quality control and research in the chemical, pharmaceutical, and biotechnology industries. To provide accurate and trustworthy findings, chromatography sample vials, a crucial part of the chromatography process, must be kept clean and free of contamination. 

It has a good washing effect on the fat-soluble residue and organic reagent residue in the 
chromatography sample vials. The cleanliness meets the requirements, the cleaning step is simple, and the cleaning time is reduced, and the cleaning process is more environmentally friendly. Please choose your own laboratory to choose your own!

At present, with the increasing attention to food quality and safety, chromatographic analysis technology is increasingly used in food quality and safety testing, especially in the field of agricultural product testing, chromatographic analysis technology has been widely used.

Every year, a large number of agricultural products (other chemical products, organic acids, etc.) are detected by liquid chromatography and gas chromatography. Due to the large number of samples, a large number of injection bottles need to be cleaned during the testing process, which not only wastes time, but also reduces work efficiency, and sometimes there is a case where the experimental results are deviated due to the cleanliness of the cleaned
chromatography sample vials.

There have five ways to clean the 
chromatography sample vials:

Method 1 :Soaking in a cleaning solution

1, tap water and rinse several times.
2, put in a beaker with pure water, and ultrasound for 15 minutes.
3, change the water, and then ultrasound for 15 minutes.
4, soaked in a beaker with water-ethanol.
5, finally take out the natural air dry.

Method 2:Dry cleaning

Using a lint-free cloth or wipe, dry cleaning is a technique for cleaning chromatography sample vials. To get rid of any impurities, wash the vials with a cloth or wipe. Then, thoroughly rinse them with deionized water and let them air dry. Vials that are not very polluted are the ideal candidates for this procedure.

Method 3: Using potassium sulfate potassium chromite lotion

1, generally with water rinse drying and then soaked with potassium sulfate potassium chromite lotion.
2, chromatography sample vials washing method and do the same other is the same, first use medical alcohol to invade more than 4 hours, and then ultrasound for half an hour, and then pour out medical alcohol, use water ultrasound half an hour, rinse with water after drying on it.

Method 4: Using Methanol

1, first with methanol (pure color spectrum) soaked, and ultrasonic cleaning for 20 minutes, then methanol dry.
2, then fill the chromatographic sample bottle with water, ultrasonic cleaning for 20 minutes, then the water will be drained.
3, after the chromatography sample bottle drying.

Method 5: Using Strong oxidation cleaning liquid

1. First with strong oxidation cleaning liquid (heavy potassium chromate) soaked for 24 hours, 
2. And then with deionized water in ultrasonic conditions cleaned three times, 
3. And finally, with methanol cleaning once, drying can be used. 

The five cleaning methods of chromatography sample vials are introduced to you. I hope you can pay attention to the cleaning of chromatographic sample bottles.

There have other three way to recommend to you:

Method 6:Alkaline cleaning

Alkali washing includes employing an alkali solution, such as a combination of sodium hydroxide and water, to clean chromatography sample vials. The alkali solution should be poured into a container before the vials are added. After soaking the vials for a few hours, thoroughly rinse them with deionized water, and then let them air dry.

Method 7:Using enzymes to clean

Enzymatic cleaning involves utilizing enzymes like amylase or protease to clean chromatography sample vials. Place the vials in the container after adding the enzyme solution to it. After soaking the vials for a few hours, thoroughly rinse them with deionized water, and then let them air dry.

Method 8 :High-pressure washing

Cleaning chromatography sample vials with a high-pressure washer is known as high-pressure washing. The vials should be placed in a basket or tray and put into the high-pressure washer. The washer cleans the vials of any impurities using high-pressure water jets. After washing, carefully rinse the vials in deionized water before allowing them to air dry.

In conclusion:

Cleaning the sample vials used for chromatography is a crucial step in the sample preparation procedure. Utilizing a cleaning technique that successfully gets rid of any impurities while guarding against vial damage is essential.

What to pay attention to:

Vial septa must be replaced with a new one, especially when analyzing pesticide residues, must change, otherwise, it will affect the quantitative results.
