This certificate is designed in accordance with ISO 17034 and ISO Guide 31. This reference material (RM) was designed,produced and verified in accordance with ISO/IEC 17025, ISO 17034 and a registered quality management system ISO 9001.
(无色液体)____
冷藏(2~8)℃,置于阴凉处
The certified value(s) and uncertainty(ies) are determined in accordance with ISO 17034 with an 95% confidence level(k=2). Uncertainty is based on the Total Combined Uncertainty, including uncertainties of characterisation, homogeneity and stability testing. Stability values are based on real evidence opposed to simulation.
The balances used for gravimetric measurements are calibrated with weights traceable to the national standards. The calibration of the balances is verified annually by an external accredited calibration service. This analysis method has been verified using an approach consistent with ISO 17034:2016 & ISO 17025:2017.

This RM is intended for use in a laboratory as a calibration and quality control standard or in method development for analytical techniques.
This reference material meets the specification stated in this certificate until the expiry date, provided it is stored unopened at the recommended temperature here in. If storage after opening is necessary, the RM should be tightly closed and kept from light and moisture.
Read Material Safety Data Sheet (MSDS) and understand any potential hazard(s) prior to the use of this product. All chemicals should be considered potentially hazardous in nature and should only be handled by qualified personnel using established good laboratory practices.
Random replicate samples of the final packaged RM have been analysed to prove homogeneity compliant with ISO 17034.
It is recommended to use 1 mg as the minimum sample size and if less material is used, to increase the certified uncertainty by a factor of two for half sample and four for a quarter of sample.Visit the support section of our website technology videos and frequently asked questions.

2.对环境的影响: 一、健康危害 侵入途径：吸入、食入。 健康危害：吸入本品可致咳嗽、呼吸困难、头痛、头晕、恶心、疲乏和四肢无力。眼和皮肤接触可致灼伤。 二、毒理学资料及环境行为 毒性：属低毒类。 急性毒性：LD5011000mg/kg(大鼠经口)；10000mg/kg(兔经皮)；LC5016g/m3(大鼠吸入)；人吸入200ppm，最小中毒浓度(刺激)。 危险特性：易燃，其蒸气与空气可形成爆炸性混合物。遇高热、明火极易燃烧爆炸。与氧化剂能发生强烈反应。接触空气或在光照条件下可生成具有潜在爆炸危险性的过氧化物。其蒸气比空气重，能在较低处扩散到相当远的地方，遇明火会引着回燃。 燃烧(分解)产物：一氧化碳、二氧化碳、硫化氢。 3.现场应急监测方法: 4.实验室监测方法: 气相色谱法，参照《分析化学手册》(第四分册，色谱分析)，化学工业出版社 5.环境标准: 6.应急处理处置方法: 一、泄漏应急处理 迅速撤离泄漏污染区人员至安全区，并进行隔离，严格限制出入。切断火源。建议应急处理人员戴自给正压式呼吸器，穿防毒服。不要直接接触泄漏物。尽可能切断泄漏源，防止进入下水道、排洪沟等限制性空间。小量泄漏：用砂土或其它不燃材料吸附或吸收。或在保证安全情况下，就地焚烧。大量泄漏：构筑围堤或挖坑收容；用泡沫覆盖，降低蒸气灾害。用防爆泵转移至槽车或专用收集器内，回收或运至废物处理场所处置。 二、防护措施 呼吸系统防护：空气中浓度较高时，建议佩戴自吸过滤式防毒面具(半面罩)。 眼睛防护：高浓度接触时，戴化学安全防护眼镜。 身体防护：穿防静电工作服。 手防护：戴防苯耐油手套。 其它：工作现场禁止吸烟、进食和饮水。工作毕，淋浴更衣。注意个人清洁卫生。 三、急救措施 皮肤接触：立即脱去被污染的衣着，用大量流动清水冲洗，至少15分钟。就医。 眼睛接触：立即提起眼睑，用大量流动清水或生理盐水彻底冲洗至少15分钟。就医。 吸入：迅速脱离现场至空气新鲜处。保持呼吸道通畅。如呼吸困难，给输氧。如呼吸停止，立即进行人工呼吸。就医。 食入：误服者用水漱口，给饮牛奶或蛋清。就医。 灭火方法：喷水冷却容器，可能的话将容器从火场移至空旷处。灭火剂：抗溶性泡沫、二氧化碳、干粉、砂土。 |
