儀器儀表

詳細(xì)說明

 測定元素 氧氮?dú)淙?nbsp;可以同時得到氧氮?dú)淙齻€元素的結(jié)果。也可以單獨(dú)作為氧氮分析,和定氫的分析。
2 分析方法 惰性氣體脈沖加熱熔融方式
O 非色散紅外吸收法檢測
N TCD熱導(dǎo)法檢測
H 非色散紅外吸收法檢測 紅外法測量氫的技術(shù)早在70年代力可的碳?xì)涞治鰞x器上就已經(jīng)成熟使用,氫的精度有保證。關(guān)于市場上其他廠商的誤導(dǎo)用戶說法,力可愿意以現(xiàn)實的調(diào)研數(shù)據(jù)說話。標(biāo)書后頁附上了TCH600在用戶處的實際調(diào)研數(shù)據(jù),以作證明。
對于氧的檢測,力可公司采用目前世界上的分析技術(shù),同時檢測CO和CO2,然后在轉(zhuǎn)化為CO2集中檢測,原理上是zui完善的,所以不僅可以保證中間量程的氧的測量精度,在超低含量和高含量的檢測范圍內(nèi)同樣可以滿足精度要求。
力可TCH600儀器精度達(dá)到0.025ppm,高于其他供貨商一個數(shù)量級,是目前市場上zui高的精度。
3 分析范圍 氧0.05ppm-5%
氮0.05ppm-3%
氫 0.1ppm-0.25% 
4 標(biāo)準(zhǔn)樣品重量 標(biāo)準(zhǔn)1.0g 
5 分析精度(重現(xiàn)性):
(氣標(biāo)) O: 0.025ppm或0.5%RSD
N: 0.025ppm或0.5%RSD
H: 0.05ppm或2%RSD 氧氮的儀器分析精度,只有力可可以達(dá)到0.025ppm.
而其他廠商zui高的精度只有0.2ppm,比力可低一個數(shù)量級。
6 靈敏度(zui小讀數(shù)) O/N/H : 0.001ppm 
7 分析時間 標(biāo)準(zhǔn)調(diào)置90秒(可根據(jù)具體分析選擇時間) 由于不再需要用色譜柱分離N2和H2,分析時間由原來180秒縮短到90秒,適合現(xiàn)場大分析量的應(yīng)用。目前只有力可公司的TCH600可以滿足這個分析時間的要求。
其他廠商單測氫的時間為180秒,而得出氧氮?dú)淙齻€結(jié)果的時間至少30分鐘,才可以保證精度。
8 脈沖電極加熱爐 1.高精度電流、電壓、功率控制功能,可以進(jìn)行程序升溫分析,而且可以進(jìn)行無極升溫。
2.爐子輸出功率:7.5KW,能滿足有色金屬、黑色金屬及各類高溫合金的檢測要求
3.電極爐自動定溫保持功能

5.五步脫氣功能:在分析時可以提前將坩鍋中的雜氣經(jīng)5步脫氣用于降低空白 1.力可升溫程序可以任意設(shè)置,而其他廠商zui多只能設(shè)定10段升溫。
2.力可儀器氣路漏氣檢查分為更詳細(xì)的4段檢漏,大大縮短了排查時間,其他廠商zui多2路檢漏。
9 水循環(huán)方式 氧氮?dú)浞治龅尼尫艤囟群芨?,大約在3000攝氏度左右,單一的內(nèi)循環(huán)無法保證*的冷卻,對儀器下電極的保護(hù)不夠。因此力可采用內(nèi)外冷卻循環(huán)水結(jié)合,確保冷卻效果。
六 分析軟件  
1 操作界面 中文、英文操作界面 力可為出廠標(biāo)準(zhǔn)配置的多語言操作平臺(內(nèi)置包括英文和中文在內(nèi)的5種語言),而其他廠商為國內(nèi)翻譯,有軟件的沖突,容易死機(jī)。
2 報表功能 標(biāo)準(zhǔn)配置(儀器軟件自帶) 
3 分析通道 氧氮?dú)渫ǖ罒o限制,用戶可自行編輯較為靈活的分析方法 其他廠商為zui多16個通道。

Oxygen, Nitrogen, and Hydrogen Determination
in Refractory Metals*
 
 
Instrument
TCH600
 
Sampling and Sample Preparation
Sampling and sample preparation of refractory metals such as titanium and zirconium is somewhat different from that of
steel. Unlike steel samples, hydrogen is not as in this group of materials; therefore, storage in liquid nitrogen or dry ice is not required. However, it is important to keep the sample cool when cutting or sectioning. Sample preparation for
oxygen and nitrogen determination has been different from that for hydrogen determination. Typically, titanium and zirconium samples are chemically etched to remove surface contamination when oxygen and nitrogen are determined. However, etching can introduce hydrogen into the sample. ASTM method
E 1409 "Determination of Oxygen and Nitrogen in Titanium and Titanium Alloys by the Inert Gas Fusion
Technique", as updated in 1996, permits either etching or abrading (filing) of the test specimen. ASTM
E 1937 "Determination of Nitrogen in Titanium and Titanium Alloys by the Inert Gas Fusion Technique" indicates that the test specimen be etched. ASTM E 1447 "Determination of Hydrogen in Titanium and Titanium Alloys by the Inert Gas Fusion Thermal Conductivity/Infrared Detection Method" permits surface preparation by abrading (if necessary to remove contamination). Differences in sample preparation

 
 
 
 
present somewhat of a dilemma regarding simultaneous determination of O, N, and H in Titanium. However, abrading samples with a file to remove surface contamination will yield accurate O, N, and H results.
