Description

用于液体的测试棒
相关申请的交叉引用
本申请要求享有于2012年11月9日提交的名为“IndicatorAndTestWandForLiquids”的美国临时专利申请号61/724,822的权益，由此其申请的全部内容，包括其公开和教导的全部通过引用并入本申请中。
发明领域
本发明的实施方案通常涉及用于测定液体样品中特定离子或其他物质的浓度的测试条，并且更尤其是，涉及一种测试棒，该测试棒具有集成到棒上的用于每个测试条的比色盒，用于指示一种特定物质是否以太高、太低或可接受的量存在。
背景技术
通常，用对特定物质敏感的指示剂组合物浸渍的滤纸条，用于这些物质的测试液体。将该条与液体接触后，该条与具有使颜色与物质浓度或在水合氢离子的情况下的pH值相关的数值标签的色图相比。这种图可以位于所述条包装上或单独的颜色表上。一旦物质的浓度被确定，测试者评估数字以确定是否必须采取补救行动，并且如果是这样的话，采取什么行动。
发明内容
通过提供用于液体中至少一种物质的测试，本发明的实施方案克服了现有技术的缺点和局限，其中用户被直接告知物质的浓度是否为高、在可接受的水平或低。
本发明实施方案的另一目的是提供一种用于游泳池(pool)或温泉(spa)中至少一种物质的测试，其中用户被直接告知物质的浓度是否为高、在可接受的水平或低。
本发明实施方案还有的另一个目的是提供一种用于游泳池或温泉中至少一种物质的测试，其中用户被直接告知物质的浓度是否为高的、在可接受的水平或低的，而不需颜色匹配。
本发明的其他目的、优点和新颖特征将在随后的说明中进行部分地阐述，并且通过阅读下文，对于本领域技术人员来说，部分将变得显而易见，或者可以通过实践本发明而学会。本发明的目的和优点可以采用在随附权利要求中特别指出的手段和组合实现和获得。
为了实现上述和其他目的并根据本发明的目的，如在此体现和广泛描述的，用于测定液体中物质浓度的测试棒在本发明包括：基板；至少一个带，在其上具有物质特异性测试组合物，所述组合物在存在特定物质的浓度范围时有效显示特定颜色，并安装在所述基板上；和至少一个标记了颜色的比较框，对应于每个集成在所述基板上的所述至少一个测试带，并设置在所述至少一个测试带的附近，使得所述至少一个测试带的颜色易于与至少一个比较框的颜色相比；从而，当所述棒浸渍在液体中时，在至少一个测试带上产生颜色。
本发明实施方案的益处和优点包括，但不局限于，提供一种物质测试棒，用于评估液体中所选物质的浓度，并指示用户需要采取的行动，而用户不必在与液体接触后将棒上带的颜色与单独的色图进行比较，并且不必评估作为标签通常与这种图谱相关联的数字。
附图说明附图包括在说明书中并构成说明书的一部分，阐明了本发明的一个实施方案，并且与描述一起用于解释本发明的原理。在图中：
图1A是测试棒的示意性表示，显示响应于研究中的诸如总碱度、TA、pH和氯、Cl浓度的物质的浓度范围，有效显示颜色的组合物的带，例如，每条带具有相应的颜色框，指示那种物质的浓度是否为高、在可接受的水平或低，而图1B示出了正被浸入含有至少一种待评估物质的液体中的棒。
具体实施方式
简而言之，本发明的实施方案包括一种用于液体的物质测试棒，其中，通过将设置在棒表面的测试条接触液体后的颜色与棒上邻近相关的且标记的彩色框进行比较，用户可以被告知特定物质的浓度是否为高、在可接受的水平或低。例如，测试棒可以用于测试游泳池和温泉中的水。
下面将详细参照本发明的实施方案，其实例在附图中示出。在图中，相似或相同的结构将使用相同的参考符号来标识。应当理解，这些图是用于说明本发明的具体实施方案，并无意于将本发明限定于此。首先看图1A，示出的是测试棒10的示意图，显示为细长的，示出了至少一个带或测试条，并且显示为组合物的带12、14和16，所述组合物用于响应至少一种研究中的物质的浓度范围而有效显示颜色，诸如总碱度、TA、pH(与溶液中水合氢离子浓度相关)和氯、Cl浓度，每个带分别具有一系列相应的标记的彩色框18、20和22，彩色框分别就近或邻近位于它们在棒10上的相关带，用于指示物质的浓度是否为高、在可接受的水平或低，而图1B示出了正被浸入液体24中的棒10，液体24含有至少一种待测物质。例如，术语“相应的”是指用于pH测量的框系列具有与表示这些标识的选定pH值或值范围相关的颜色。由于用户被告知对于液体样品中至少一种物质的情况，用户会立即清楚需要采取什么行动。例如，如果水样品取自一个游泳池，并且棒的结果是pH高，则测试后测试棒告知用户必须添加试剂到游泳池以降低pH值。可以通过将所有的带同时浸入液体中同时进行不同物质的测试。
反应带包括用对测试液体中特定物质敏感的指示剂浸渍的纤维素和非纤维素纤维材料，并用粘合剂安装在基板上。使用双面粘合纸安装在聚苯乙烯棒上的浸渍的滤纸条是这种带的一个实例。
彩色比较框设置在反应测试区域的附近或邻近，由此提供一种便利的方法用于颜色比较和确定每个化学指标的测试水平，如同从图1A可以观察到的，采用灰色调显示颜色。可以通过采用不溶性的墨打印将框集成到棒上，或者可以利用透明的、不透水的涂层涂覆打印的框，以保护框免受正在测试的液体的损害。如果棒是由疏水性材料制成，墨也可以是疏水性的，并且不因为短的棒浸入时间而被液体样品降解。
作为一个实例，标识可以包括：用于指示低于推荐的浓度的“LOW”，用于指示适当浓度的“OK”，以及用于指示高于推荐范围的浓度的“HIGH”。同时，图1A中示出的是用于测试带的识别字母，总碱度(“TA”)、“pH值”和游离氯“Cl”。图1B示出了正被放置在用于同时检测这些物质的液体中的受试棒。作为实例，在图1B中，看到“TA”带对应于“OK”框，“pH值”对应于与“HIGH”框，“Cl”对应于“LOW”框。
显然，具有相同反应性化学的多个带，例如，pH可以放置在棒上，通过每次只将一个未使用的测试带浸入液体，用于利用单个棒的液体的顺序测试。
本发明的上述描述用于说明和描述的目的，并且上述描述不是穷举的或将本发明限制为所公开的精确形式，并且显然地，根据上述教导许多修改和变化是可能的。为了最好地解释本发明的原理及其实际应用，选择并描述了实施方案，从而使得本领域的其他技术人员能够在各种实施方案中最佳地利用本发明并针对所设想的特定用途进行各种变更。本发明的范围通过本发明随附的权利要求来确定。
