Industrial Test Systems Quick 481396 Arsenic for Water Quality Testing, 100 Tests, 12 Minutes Test Time

Here is a short description of what I use it for and why I bought When I bought my house, I was told that the water in my well was arsenic-contaminated. In the past, since I could not afford an expensive filtration system, I have gotten water delivered to me. It is heavy to deliver these jugs (for the water cooler), and I did not want to be frustrated by the drive as well as the expense. A couple of weeks ago, I decided to re-research the topic in order to see if it was still possible to find affordable filtration methods. In searching for the Berkey filter system, I came across a filtering and cleansing system that seemed impressive They say it probably stops filtering arsenic "long before the life of the filter" but exactly how much earlier Although they offer an additional arsenic filter we can add on to our system, I hesitated to purchase it for reasons I won't go into here. I've also read mixed reviews on these kinds of filters. To clarify, if the primary filters are effective in filtering arsenic, I was wondering how long the primary black filters alone will last for the purpose of removing As a result, I decided to do an experiment myself. Both the Berkey and this kit were purchased by me. An initial professional analysis of my water was conducted at a lab and the results were both The total EPA recommended limit is 0. The result is 014ppm, which is over the maximum limit. Although not a large difference, 010ppm (or 10 ppb) is slightly higher than the norm. Therefore, my plan is to make use of this kit to test my filtered water every month until I gauge how long the filters will remain effective in trapping arsenic before they need to be replaced. I prefer to use this kit because I am not able to pay for professional lab testing monthly, so I am very happy to find this kit of 100 tests that I can perform myself. When I am performing the test, I feel a bit like a mad scientist, you have to add this agent, then shake it, add another, shake it, There is very limited time to complete all the steps, so I strongly recommend reading the instructions and tips sections of the enclosed booklet before you attempt any tests. After a few tests, it becomes very easy, but you must pay attention to all the steps of the test after each test. I was lucky in my case, however, as I knew exactly how much arsenic was in my tap water from the lab results, so that made things simpler. The first thing I did when I got the kit was to test We recommend using filtered water as a control first. As part of the kit you will find a numbered color chart that ranges from deep orange (high arsenic) to pale yellow (low arsenic), and of course white is non Unfortunately, in my case I had some difficulties, as my arsenic levels were low, so I had a difficult time matching the palest yellow shades. There is only 30 seconds available to match the result strip to the color chart before it fades, and those 30 seconds go incredibly fast! The low end of the chart ranges from 0ppb, then 5, then 10, then 20, then up to over 500! My lab results indicated that my control sample would be darker than 10 but lighter than 20, since my lab test was As far as my first test result goes, I wasn't sure if it was a 0 or a 5, and my second attempt seemed to be a While I recognize that arsenic levels in well water can vary over time, this still seemed a bit confusing and my results were unclear. A test of my FILTERED water revealed that the result was 0ppb, the water was white on the strip and no contamination was found The chart below shows the results. discussed the situation with a friend who is a chemist and he suggested that I try again My artificial lighting made it difficult to do the test inside. I decided to perform the test outside. "Natural daylight" is described as ideal in the manual. Also, I read more of the manual and noted that it mentions that the water temperature is critical to a successful process. The temperature should be between 72 and 76 degrees Fahrenheit It is possible for a "false low" to happen with water that is too cold, 84 degrees F. A sample may have been too cold, which is why I suspected it Thus, I went back to the unfiltered water test the next day and let it warm up in the sun for a few minutes in order to ensure it was warm enough. Therefore I had to guess, but for the most part I just made sure it felt warmer Additionally, I did this third test outdoors, not in direct sunlight but in the After making these two changes, I managed to get a clear reading of 10ppb once again. The shade (though still pale) was much easier to match to the chart and I had a better chance of matching it to the chart. Maybe a bit darker, but nearer to a perfect match for 10, and definitely lighter than twenty. As such, this was in line with the 14 that I know of in my lab results. My purpose in telling you all of this is to help anyone who needs it You need both a temperature that's right for the water and adequate daylight lighting! The only flaw I would find in this kit is that a special thermometer really ought to be included, since proper water temperature appears to be crucial for good All the labels are clearly labelled, and the directions are very good once you take the time to read them. As well as the general troubleshooting guide, the manual cites a list of problems, along with probable causes and possible solutions. A specific part I like is the kit container, which contains everything neatly and allows for easy storage. As a result of a few trial runs, I've obtained what I believe are accurate results, and I'm thrilled to find that my arsenic is being removed by the filter. As a result, I will proceed with this kit every month until I can figure out how long my water filters will last.

In many years of working in chemistry, I have gained a great deal of knowledge. As some of the wells in the area were rumored to be contaminated with arsenic, I wanted to test my water for the substance. It is easy to follow the instructions for taking the test. My favorite thing about the sample preparation process is that it condenses both of the arsenic oxidation states (+3, +5). I have used other tests that detected oxidation only in one or the other state in the past. As far as I can tell, the only problem with the testing system is it should have included a standard solution containing arsenic at a known concentration, so that you could verify that the procedure was being applied.

I like it.
