Description :

　　In the process of water quality testing, the collection and storage of water samples are important links in water quality analysis. In order to obtain accurate and comprehensive water quality analysis data, it is necessary to adopt correct sampling methods and water sample preservation methods, and timely send samples for analysis and testing. The correct sampling and storage methods are prerequisites for obtaining reliable detection results.

　　Since the collection and storage of water samples are so crucial, what are the requirements for the collection and storage of water samples by portable sewage samplers? What should we pay attention to?

　　1. Water sample collection

　　(1) Select specific sampling locations to avoid contamination of the sampler or sampling device inlet by the surrounding environment, including the possibility of sampler finger contamination. Especially when collecting water samples with microbial indicators, strict sterility is required before use, so the container must be sterilized by dry heat or wet heat.

　　(2) Before sampling with the inlet sampler, water should be drained for a few minutes, especially when using pumping equipment to collect tap water or well water, to flush out impurities accumulated in the water pipe or sampler pipeline.

　　(3) After collecting the water sample, immediately label the water container (water sample bottle) or record it in detail in the water sample manual. The content of the water sample manual should include the location, date, time, water source type, water sample, water level, surrounding water sources and discharge outlets, water temperature, air temperature, climate conditions, analysis purpose and items, as well as the person who sampled the water.

　　2. Preservation of water samples

　　After using an automatic water quality sampler to collect water samples, analysis and inspection should be carried out as soon as possible. Some projects also require on-site measurement of dissolved oxygen, carbon dioxide, free chlorine, etc. in water. However, due to various limitations such as instruments, venues, etc., only a few measurement items (temperature, conductivity, pH value, etc.) can often be carried out on-site, and most items still need to be sent to the laboratory for measurement.

　　Therefore, the preservation of water samples is a very important issue. After water sample collection, if not stored properly, substances in the water often undergo physical, chemical, and biological changes.

　　As a salesperson, I can't be overly emotional because that's not me. Talking to clients with vitality every day is the joy of my work. Occasionally, when I'm busy, I forget about the time or feel like there's not enough time, so I cherish my clients and our friendship very much!

　　I posted on my social media account about my performance at the end of a month. My old customer saw my social media account and immediately told me to stock up and asked me to make a contract for him. No matter how much or less, at least our long-standing friendship has moved me. We have known each other for about seven years, from our previous company in 2016 to now, and even when I started my own company, he still supports me as always. I have made up my mind that as long as I produce environmentally friendly instruments and sell from my company, I will definitely not disappoint my customers. Some customers have been with me for a long time, and that is a friendship. Don't talk about money, it's mainly about friendship.

　　Knowing that my new company has been established, I even instructed their employees to come to me for cooperation with orders, which moved me deeply. Whether it's their suppliers or their customers, it's really lucky to have such a boss. I remember a few years ago, he told me that they serve customers well, whether it's instrument performance or post training. As a manufacturer, I often respect him as my big brother because there are many things I can learn from him. With excellent people, I will learn a lot. If you go far, you will also excel.

　　So when it comes to environmental instruments, I take it seriously and treat customers with sincerity. I guarantee that every customer can use our equipment with peace of mind and satisfaction. After sales, we provide one-on-one technical guidance and use our sincerity and quality to safeguard our customers' pre-sales and after-sales service, ensuring that every customer can rest assured and satisfied, and thus establishing our long-term cooperation!
