詳情介紹

詳細(xì)說明:

測(cè)定元素氧氮?dú)淙?nbsp;可以同時(shí)得到氧氮?dú)淙齻€(gè)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(cè)
N TCD熱導(dǎo)法檢測(cè)
H 非色散紅外吸收法檢測(cè) 紅外法測(cè)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(chǎng)上其他廠商的誤導(dǎo)用戶說法，力可愿意以現(xiàn)實(shí)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(shí)際調(diào)研數(shù)據(jù)，以作證明。
對(duì)于氧的檢測(cè)，力可公司采用目前世界上的分析技術(shù)，同時(shí)檢測(cè)CO和CO2，然后在轉(zhuǎn)化為CO2集中檢測(cè)，原理上是zui完善的，所以不僅可以保證中間量程的氧的測(cè)量精度，在超低含量和高含量的檢測(cè)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(gè)數(shù)量級(jí)，是目前市場(chǎng)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(gè)數(shù)量級(jí)。
6 靈敏度（zui小讀數(shù)） O/N/H : 0.001ppm
7 分析時(shí)間標(biāo)準(zhǔn)調(diào)置90秒（可根據(jù)具體分析選擇時(shí)間）由于不再需要用色譜柱分離N2和H2，分析時(shí)間由原來180秒縮短到90秒，適合現(xiàn)場(chǎng)大分析量的應(yīng)用。目前只有力可公司的TCH600可以滿足這個(gè)分析時(shí)間的要求。
其他廠商單測(cè)氫的時(shí)間為180秒，而得出氧氮?dú)淙齻€(gè)結(jié)果的時(shí)間至少30分鐘，才可以保證精度。

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(shí)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(duì)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。

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.
