Please tell us the background behind the selection of \u03c9 series.&#8221;<\/p><dl class=\"voice-dl\"><dt class=\"voice-takaku\">Mr. Takaku<\/dt><dd><p>With ordinary ultrapure water equipment, the specifications are decided by the manufacturer, and it would be hard to make it custom-made. If we want to order a custom-made product, we have to install a large equipment such as for a large plant scale. A small scale like many laboratories usually does not require such a large scale. Organo has the know-how to make custom-made ultrapure water equipment for large plants, and it is also considered to be able to supply the parts and consumables individually.<\/p><\/dd><dt class=\"voice-organo\">Mr. Nishimura<\/dt><dd><p>If very strict ultrapure water quality is required for analysis, it is certainly necessary to have &#8220;custom-made&#8221; like a large plant, but it will be often too much equipment and also difficult in terms of laboratory space. However, the highly required water quality may not be achieved with ready-made products.<\/p><\/dd><dt class=\"voice-takaku\">Mr. Takaku<\/dt><dd><p>It has been more than 10 years since I came here (Institute for Environmental Science), and during that time I have been receiving parts and consumables for plant use and also information on upgrades from Organo. We have been appreciating Organo with such know-how and various important information.<br \/>For example, we may require the different water purity levels that were not initially needed and also technologies that remove only specific elements. It is very helpful to be able to incorporate such special technologies into existing equipment.<\/p><\/dd><\/dl><div class=\"voice-img\"><div class=\"block2\"><img decoding=\"async\" src=\"https:\/\/puric.organo.co.jp\/module\/wp-content\/uploads\/2021\/03\/img_voice01_background01.jpg\" alt=\"custom-made ultrapure water equipments.\" \/><p>Organo has the know-how to make large plants but also small standard products, so it is possible to make custom-made ultrapure water equipments.<\/p><\/div><div class=\"block2\"><img decoding=\"async\" src=\"https:\/\/puric.organo.co.jp\/module\/wp-content\/uploads\/2021\/03\/img_voice01_background02.jpg\" alt=\"\" \/><\/div><\/div><div class=\"voice-point\"><h3>Reason of selecting \u03c9 series<\/h3><p>Especially with ultrapure water required for advanced trace element analysis, it was a good example to fully show the performance of \u03c9 series.

But it is the good point of \u03c9 series that Organo is able to meet it as a standard product.<br \/>Next, we will move to the further topic about the performance of \u03c9 series.<\/p><\/div><\/div><\/div><div class=\"anker-contents\" id=\"point\"><div class=\"contents\"><h2><span>Strength of \u03c9 series<\/span><\/h2><p>High level is always required for the Institute for Environmental Science.<br \/>What are the strengths of \u03c9 series which can meet the high requirements.<\/p><div class=\"voice-img03-l\"><img decoding=\"async\" src=\"https:\/\/puric.organo.co.jp\/module\/wp-content\/uploads\/2021\/03\/img_voice01_point01.jpg\" alt=\"Mr.Takaku\" \/><\/div><dl class=\"voice-dl\"><dt class=\"voice-takaku\">Mr. Takaku<\/dt><dd><p>The strength of \u03c9 series is the ultrapure water quality level equivalent to the plant level even by a small scale. Furthermore, it also would be good to be able to control TOC for some analysis. The analysis-related industries would appreciate the capability.<\/p><\/dd><dt class=\"voice-organo\">Mr. Nishimura<\/dt><dd><p>Mentioning the plant level, is it ultrapure water quality used for semiconductor cleaning process?<\/p><\/dd><dt class=\"voice-takaku\">Mr. Takaku<\/dt><dd><p>That&#8217;s right. The ultrapure water, which is used in the so-called &#8220;32 mega \/ 64 mega&#8221; DRAM production line, could be sampled. It is the strength that this level of water can be achieved with the small scale of the standard equipment.<\/p><\/dd><dt class=\"voice-organo\">Mr. Nishimura<\/dt><dd><p>You also mentioned TOC. Do you think that TOC management and control are necessary even for such standard equipment?<\/p><\/dd><dt class=\"voice-takaku\">Mr. Takaku<\/dt><dd><p>It is important where the TOC is controlled by the plant-level equipment and also where organic analysis, especially trace organic analysis is conducted.<\/p><\/dd><\/dl><div class=\"voice-point\"><h3>Strength of \u03c9 series<\/h3><p>The reduction and control of TOC (TOC \u2264 1ppb) are considered as the greatest feature of \u03c9 series.<br \/>The required water quality is evolving along with the technological evolution of semiconductor industry.<br \/>Next, we would like to move the topic about why \u03c9 series is to be recommended.<\/p><\/div><\/div><\/div><div class=\"anker-contents\" id=\"reason\"><div class=\"contents\"><h2><span>Reason for recommending \u03c9 series<\/span><\/h2><p>The real opinion from the actual use.<br \/>We asked Mr. Takaku why he recommends \u03c9 series.<\/p><div class=\"voice-img03-l\"><img decoding=\"async\" src=\"https:\/\/puric.organo.co.jp\/module\/wp-content\/uploads\/2021\/03\/img_voice01_reason03.jpg\" alt=\"ion exchange resin cartridges\" \/><p>\u03c9 series is equipped with multi-stage treatment ion exchange resin cartridges.<\/p><\/div><dl class=\"voice-dl\"><dt class=\"voice-takaku\">Mr. Takaku<\/dt><dd><p>First of all, it is compact and functional.<br \/>It would be notable that the quality of plant-level (large-scale) ultrapure water can be achieved with the standard equipment.<\/p><\/dd><dt class=\"voice-organo\">Mr. Nishimura<\/dt><dd><p>Thank you for your explanation. Then, how about the usability?<br \/>\u03c9 series is equipped with the function of a foot switch and collecting a single drop of water.<\/p><\/dd><dt class=\"voice-takaku\">Mr. Takaku<\/dt><dd><p>The foot switch is very important in my opinion.<br \/>It is a great feature to sample water without touching the equipment directly with our hands. As during the analysis most of the work is done with gloves, the equipment would be often hard to react with the gloves&#8217; touching operation. Hence, &#8220;Hands free&#8221; is an important factor us.<br \/>A single drop function would be a unique feature, but we don&#8217;t use it much for our analysis purposes.<br \/>It should be useful in sample preparation for organic experiments. The amount is controlled by volume in normal analysis, but since we control it by weight, we do not adjust the volume by a single drop function.<\/p><\/dd><dt class=\"voice-organo\">Mr. Nishimura<\/dt><dd><p>Indeed, the volume of water changes depending on the temperature. As 100ml would not be always 100g, in such cases, a single drop function may not be useful.<\/p><\/dd><dt class=\"voice-takaku\">Mr. Takaku<\/dt><dd><p>When ultrapure water with the same quality level as the plant is required, we should prepare complicated multi-stage treatments.<br \/>It includes not only the ion exchange resin cartridges but also the membrane and other processes.<br \/>When we prepare multi-stage processes, the system becomes complicated and large-scale. But to my surprise, \u03c9 series incorporates such processes for pursuing the performance by the standard model.<\/p><\/dd><\/dl><div class=\"voice-img\"><div class=\"block2\"><img decoding=\"async\" src=\"https:\/\/puric.organo.co.jp\/module\/wp-content\/uploads\/2021\/03\/img_voice01_reason01.jpg\" alt=\"\" \/><\/div><div class=\"block2\"><img decoding=\"async\" src=\"https:\/\/puric.organo.co.jp\/module\/wp-content\/uploads\/2021\/03\/img_voice01_reason02.jpg\" alt=\"\" \/><\/div><\/div><div class=\"voice-point\"><h3>Reason for recommending \u03c9 series<\/h3><p>As we mentioned the water quality of \u03c9 series in the previous page, here we more focused on the usability of \u03c9 series, which the customer felt from the actual use. \u03c9 series has too many other functions to explain all in few pages.

I was learning by trial and error in such a way as introducing MS (mass spectrometer), changing the pretreatment, or extracting and fractionating, etc.<br \/>I feel that Organo\u2019s ultrapure water technology for semiconductors is growing in line with responding to Mr. Takaku\u2019s demand.<br \/>I was also talking with reagent manufacturers and once I was helping to decide on a JIS(Japanese Industrial Standard) analysis method for ultra high purity reagents.<\/p><\/dd><dt class=\"voice-organo\">Mr. Nishimura<\/dt><dd><p>By listening to your precious story and opinions, we will understand your achievements and appreciate your work contributed to our industry.<br \/>We will keep meeting the customer needs like you, who tries to lead the industry and develop further steps to the future.<\/p><\/dd><\/dl><div class=\"voice-point\"><h3>After the interview<\/h3><p>To Organo, it is a precious opportunity to have an interview the users about how they use our products actually.
