The Pittsburgh Conference (Pittcon) was held in Chicago in March 2020, immediately before worldwide coronavirus disease 2019 (COVID-19) restrictions came into place. The attendance then was down from previous years, and it was noticeable that airports were deserted. Therefore Pittcon 2023, held in Philadelphia, Pennsylvania was the first chance for many people to get together in more than three years. The Philadelphia Convention Center is built around a former railway terminus, with reminders of its older purpose still visible, and part of it sits above a large, very popular indoor market (Figure 1). The Symposium “Frontiers of Near-Infrared Spectroscopy in Analytical Applications” was organized by Krzysztof Bec and Christian Huck (University of Innsbruck). Unfortunately, COVID-19 still affected the Symposium and three of the speakers were unable to attend. At short notice the author of this summary (Figure 2) was asked to step in to chair the session, and he used the available time to allow the speakers to overrun their normal time allocation, and to have a fruitful panel discussion, so that there were no gaps in the schedule (Figure 3). Richard Crocombe’s (Crocombe Spectroscopic Consulting) talk was about “Miniature Optical Spectrometers and Multispectral Sensors in Consumer Goods and Wearables”. He described the latest development in portable spectroscopy, the availability of very low-cost multispectral sensors, about the size of computer chips, leading to the possibility of embedding them into consumer goods. Multispectral devices can be produced in volume via semiconductor and optical coating techniques, at very low cost – less than $10 each. Multispectral sensors can now not only be incorporated into ‘white goods’ like washing machines and dryers, but also into ‘fitness’ products like smart watches and sports watches, and as photonic miniaturization increases, into ‘wearables’ like smart rings, providing the user with health information. Silicon photonics and photonic integrated circuits, produced en masse using semiconductormanufacturing techniques, are the ideal next step. The presentation surveyed the field, and highlighted some ‘smart’ consumer device possibilities, from toothbrushes to toilets. Boris Mizaikoff’s (Ulm University and HahnSchickard) talk was on “Midvs. Near-Infrared Spectroscopy: Challenges and Potential”. He discussed the miniaturization of spectrometers and advances in fiber-optic devices and spectral data processing which make NIRS a powerful analytical technology for its implementation at various points along the entire food chain to meet the growing demands of food product control. The portability of the latest generation miniaturized NIR systems makes their application for the quality and authentication control and monitoring of a wide range of food products feasible, to provide challenging solutions to specific demands of the food industry that were completely unthinkable and unaffordable before these developments.
匹兹堡会议于2020年3月在芝加哥举行，就在全球2019冠状病毒病(COVID-19)限制措施实施之前。当时的出席人数比前几年有所下降，值得注意的是机场空无一人。因此，在宾夕法尼亚州费城举行的Pittcon 2023是许多人三年多来第一次聚在一起的机会。费城会议中心建在以前的铁路总站周围，仍然可以看到它的旧用途，它的一部分位于一个非常受欢迎的大型室内市场上方(图1)。研讨会“近红外光谱分析应用的前沿”是由Krzysztof Bec和Christian Huck(因斯布鲁克大学)组织的。不幸的是，2019冠状病毒病仍然影响了研讨会，三位发言人无法出席。在很短的时间内，这篇摘要的作者(图2)被要求介入主持会议，他利用可用的时间让演讲者超出他们的正常时间分配，并进行了富有成效的小组讨论，因此时间表上没有空白(图3)。Richard Crocombe (Crocombe Spectroscopic Consulting)的演讲是关于“微型光学光谱仪和多光谱传感器在消费品和可穿戴设备”。他描述了便携式光谱学的最新发展，即非常低成本的多光谱传感器的可用性，其大小与计算机芯片差不多，从而有可能将其嵌入消费品中。多光谱器件可以通过半导体和光学涂层技术批量生产，成本非常低——每个不到10美元。多光谱传感器现在不仅可以集成到洗衣机和烘干机等“白色家电”中，还可以集成到智能手表和运动手表等“健身”产品中，随着光子小型化的增加，还可以集成到智能戒指等“可穿戴设备”中，为用户提供健康信息。利用半导体制造技术大规模生产的硅光子学和光子集成电路是理想的下一步。该演讲调查了这一领域，并强调了一些“智能”消费设备的可能性，从牙刷到厕所。Boris Mizaikoff(乌尔姆大学和HahnSchickard)的演讲是关于“Midvs”的。近红外光谱学:挑战与潜力”他讨论了光谱仪的小型化以及光纤设备和光谱数据处理的进步，这些都使近红外光谱成为一种强大的分析技术，可以在整个食物链的各个环节实施，以满足日益增长的食品控制需求。最新一代小型化近红外系统的便携性使其适用于各种食品的质量和认证控制和监控，为食品行业的特定需求提供具有挑战性的解决方案，这些需求在这些发展之前是完全不可想象和负担不起的。一些例子显示了直接在田间使用近红外光谱对园艺产品的收获提出建议，或在活体动物分析中评估特定质量参数。Jerome Workman, Jr (MJH Life Sciences)描述了固态近红外分析:构建多个相同的仪器，没有移动部件，3D打印底盘和校准转移技术。他提出了一个问题，如何建立一个高性能，低维护，并允许精确校准转移的固态近红外分光光度计?校准转移是指仪器技术和化学计量学技术的结合，用于尝试应用单一光谱数据库，以及使用该数据库开发的校准模型，用于两个或多个仪器，保持准确性和精密度。他的演讲讨论了与基于微机电系统数字光处理(MEMS-DLP)的分光光度计开发相关的技术方面和挑战，结合3D打印光学底盘，以及用于自动仪器校准的ai型软件功能，以说明未来仪器设计和制造的模型。Dolores(“Lola”)P erez Mar ın(科尔多瓦大学)讨论了便携式近红外光谱传感器，以增加农业食品控制的解决方案。她描述了近红外传感器是如何实现快速、准确、非破坏性、低成本和高效的

In this study, we present a chemometric procedure called ‘Specific Normalization’. It upgrades the calibration for use in a specific set of new samples by normalizing together the spectra of both the calibration set and a new measured sample set. The proposed procedure is shown for near infra-red spectroscopy measurement of olive oil acidity, as an example. This procedure would need its integration as software application for routine analysis.
